:mod:`asynchat` --- Asynchronous socket command/response handler
================================================================
.. module:: asynchat
:synopsis: Support for asynchronous command/response protocols.
.. moduleauthor:: Sam Rushing <rushing@nightmare.com>
.. sectionauthor:: Steve Holden <sholden@holdenweb.com>
**Source code:** :source:`Lib/asynchat.py`
.. deprecated:: 3.6
Please use :mod:`asyncio` instead.
--------------
.. note::
This module exists for backwards compatibility only. For new code we
recommend using :mod:`asyncio`.
This module builds on the :mod:`asyncore` infrastructure, simplifying
asynchronous clients and servers and making it easier to handle protocols
whose elements are terminated by arbitrary strings, or are of variable length.
:mod:`asynchat` defines the abstract class :class:`async_chat` that you
subclass, providing implementations of the :meth:`collect_incoming_data` and
:meth:`found_terminator` methods. It uses the same asynchronous loop as
:mod:`asyncore`, and the two types of channel, :class:`asyncore.dispatcher`
and :class:`asynchat.async_chat`, can freely be mixed in the channel map.
Typically an :class:`asyncore.dispatcher` server channel generates new
:class:`asynchat.async_chat` channel objects as it receives incoming
connection requests.
.. class:: async_chat()
This class is an abstract subclass of :class:`asyncore.dispatcher`. To make
practical use of the code you must subclass :class:`async_chat`, providing
meaningful :meth:`collect_incoming_data` and :meth:`found_terminator`
methods.
The :class:`asyncore.dispatcher` methods can be used, although not all make
sense in a message/response context.
Like :class:`asyncore.dispatcher`, :class:`async_chat` defines a set of
events that are generated by an analysis of socket conditions after a
:c:func:`select` call. Once the polling loop has been started the
:class:`async_chat` object's methods are called by the event-processing
framework with no action on the part of the programmer.
Two class attributes can be modified, to improve performance, or possibly
even to conserve memory.
.. data:: ac_in_buffer_size
The asynchronous input buffer size (default ``4096``).
.. data:: ac_out_buffer_size
The asynchronous output buffer size (default ``4096``).
Unlike :class:`asyncore.dispatcher`, :class:`async_chat` allows you to
define a :abbr:`FIFO (first-in, first-out)` queue of *producers*. A producer need
have only one method, :meth:`more`, which should return data to be
transmitted on the channel.
The producer indicates exhaustion (*i.e.* that it contains no more data) by
having its :meth:`more` method return the empty bytes object. At this point
the :class:`async_chat` object removes the producer from the queue and starts
using the next producer, if any. When the producer queue is empty the
:meth:`handle_write` method does nothing. You use the channel object's
:meth:`set_terminator` method to describe how to recognize the end of, or
an important breakpoint in, an incoming transmission from the remote
endpoint.
To build a functioning :class:`async_chat` subclass your input methods
:meth:`collect_incoming_data` and :meth:`found_terminator` must handle the
data that the channel receives asynchronously. The methods are described
below.
.. method:: async_chat.close_when_done()
Pushes a ``None`` on to the producer queue. When this producer is popped off
the queue it causes the channel to be closed.
.. method:: async_chat.collect_incoming_data(data)
Called with *data* holding an arbitrary amount of received data. The
default method, which must be overridden, raises a
:exc:`NotImplementedError` exception.
.. method:: async_chat.discard_buffers()
In emergencies this method will discard any data held in the input and/or
output buffers and the producer queue.
.. method:: async_chat.found_terminator()
Called when the incoming data stream matches the termination condition set
by :meth:`set_terminator`. The default method, which must be overridden,
raises a :exc:`NotImplementedError` exception. The buffered input data
should be available via an instance attribute.
.. method:: async_chat.get_terminator()
Returns the current terminator for the channel.
.. method:: async_chat.push(data)
Pushes data on to the channel's queue to ensure its transmission.
This is all you need to do to have the channel write the data out to the
network, although it is possible to use your own producers in more complex
schemes to implement encryption and chunking, for example.
.. method:: async_chat.push_with_producer(producer)
Takes a producer object and adds it to the producer queue associated with
the channel. When all currently-pushed producers have been exhausted the
channel will consume this producer's data by calling its :meth:`more`
method and send the data to the remote endpoint.
.. method:: async_chat.set_terminator(term)
Sets the terminating condition to be recognized on the channel. ``term``
may be any of three types of value, corresponding to three different ways
to handle incoming protocol data.
+-----------+---------------------------------------------+
| term | Description |
+===========+=============================================+
| *string* | Will call :meth:`found_terminator` when the |
| | string is found in the input stream |
+-----------+---------------------------------------------+
| *integer* | Will call :meth:`found_terminator` when the |
| | indicated number of characters have been |
| | received |
+-----------+---------------------------------------------+
| ``None`` | The channel continues to collect data |
| | forever |
+-----------+---------------------------------------------+
Note that any data following the terminator will be available for reading
by the channel after :meth:`found_terminator` is called.
.. _asynchat-example:
asynchat Example
----------------
The following partial example shows how HTTP requests can be read with
:class:`async_chat`. A web server might create an
:class:`http_request_handler` object for each incoming client connection.
Notice that initially the channel terminator is set to match the blank line at
the end of the HTTP headers, and a flag indicates that the headers are being
read.
Once the headers have been read, if the request is of type POST (indicating
that further data are present in the input stream) then the
``Content-Length:`` header is used to set a numeric terminator to read the
right amount of data from the channel.
The :meth:`handle_request` method is called once all relevant input has been
marshalled, after setting the channel terminator to ``None`` to ensure that
any extraneous data sent by the web client are ignored. ::
import asynchat
class http_request_handler(asynchat.async_chat):
def __init__(self, sock, addr, sessions, log):
asynchat.async_chat.__init__(self, sock=sock)
self.addr = addr
self.sessions = sessions
self.ibuffer = []
self.obuffer = b""
self.set_terminator(b"\r\n\r\n")
self.reading_headers = True
self.handling = False
self.cgi_data = None
self.log = log
def collect_incoming_data(self, data):
"""Buffer the data"""
self.ibuffer.append(data)
def found_terminator(self):
if self.reading_headers:
self.reading_headers = False
self.parse_headers(b"".join(self.ibuffer))
self.ibuffer = []
if self.op.upper() == b"POST":
clen = self.headers.getheader("content-length")
self.set_terminator(int(clen))
else:
self.handling = True
self.set_terminator(None)
self.handle_request()
elif not self.handling:
self.set_terminator(None) # browsers sometimes over-send
self.cgi_data = parse(self.headers, b"".join(self.ibuffer))
self.handling = True
self.ibuffer = []
self.handle_request()

:mod:`asyncore` --- Asynchronous socket handler
===============================================
.. module:: asyncore
:synopsis: A base class for developing asynchronous socket handling
services.
.. moduleauthor:: Sam Rushing <rushing@nightmare.com>
.. sectionauthor:: Christopher Petrilli <petrilli@amber.org>
.. sectionauthor:: Steve Holden <sholden@holdenweb.com>
.. heavily adapted from original documentation by Sam Rushing
**Source code:** :source:`Lib/asyncore.py`
.. deprecated:: 3.6
Please use :mod:`asyncio` instead.
--------------
.. note::
This module exists for backwards compatibility only. For new code we
recommend using :mod:`asyncio`.
This module provides the basic infrastructure for writing asynchronous socket
service clients and servers.
There are only two ways to have a program on a single processor do "more than
one thing at a time." Multi-threaded programming is the simplest and most
popular way to do it, but there is another very different technique, that lets
you have nearly all the advantages of multi-threading, without actually using
multiple threads. It's really only practical if your program is largely I/O
bound. If your program is processor bound, then pre-emptive scheduled threads
are probably what you really need. Network servers are rarely processor
bound, however.
If your operating system supports the :c:func:`select` system call in its I/O
library (and nearly all do), then you can use it to juggle multiple
communication channels at once; doing other work while your I/O is taking
place in the "background." Although this strategy can seem strange and
complex, especially at first, it is in many ways easier to understand and
control than multi-threaded programming. The :mod:`asyncore` module solves
many of the difficult problems for you, making the task of building
sophisticated high-performance network servers and clients a snap. For
"conversational" applications and protocols the companion :mod:`asynchat`
module is invaluable.
The basic idea behind both modules is to create one or more network
*channels*, instances of class :class:`asyncore.dispatcher` and
:class:`asynchat.async_chat`. Creating the channels adds them to a global
map, used by the :func:`loop` function if you do not provide it with your own
*map*.
Once the initial channel(s) is(are) created, calling the :func:`loop` function
activates channel service, which continues until the last channel (including
any that have been added to the map during asynchronous service) is closed.
.. function:: loop([timeout[, use_poll[, map[,count]]]])
Enter a polling loop that terminates after count passes or all open
channels have been closed. All arguments are optional. The *count*
parameter defaults to ``None``, resulting in the loop terminating only when all
channels have been closed. The *timeout* argument sets the timeout
parameter for the appropriate :func:`~select.select` or :func:`~select.poll`
call, measured in seconds; the default is 30 seconds. The *use_poll*
parameter, if true, indicates that :func:`~select.poll` should be used in
preference to :func:`~select.select` (the default is ``False``).
The *map* parameter is a dictionary whose items are the channels to watch.
As channels are closed they are deleted from their map. If *map* is
omitted, a global map is used. Channels (instances of
:class:`asyncore.dispatcher`, :class:`asynchat.async_chat` and subclasses
thereof) can freely be mixed in the map.
.. class:: dispatcher()
The :class:`dispatcher` class is a thin wrapper around a low-level socket
object. To make it more useful, it has a few methods for event-handling
which are called from the asynchronous loop. Otherwise, it can be treated
as a normal non-blocking socket object.
The firing of low-level events at certain times or in certain connection
states tells the asynchronous loop that certain higher-level events have
taken place. For example, if we have asked for a socket to connect to
another host, we know that the connection has been made when the socket
becomes writable for the first time (at this point you know that you may
write to it with the expectation of success). The implied higher-level
events are:
+----------------------+----------------------------------------+
| Event | Description |
+======================+========================================+
| ``handle_connect()`` | Implied by the first read or write |
| | event |
+----------------------+----------------------------------------+
| ``handle_close()`` | Implied by a read event with no data |
| | available |
+----------------------+----------------------------------------+
| ``handle_accepted()``| Implied by a read event on a listening |
| | socket |
+----------------------+----------------------------------------+
During asynchronous processing, each mapped channel's :meth:`readable` and
:meth:`writable` methods are used to determine whether the channel's socket
should be added to the list of channels :c:func:`select`\ ed or
:c:func:`poll`\ ed for read and write events.
Thus, the set of channel events is larger than the basic socket events. The
full set of methods that can be overridden in your subclass follows:
.. method:: handle_read()
Called when the asynchronous loop detects that a :meth:`read` call on the
channel's socket will succeed.
.. method:: handle_write()
Called when the asynchronous loop detects that a writable socket can be
written. Often this method will implement the necessary buffering for
performance. For example::
def handle_write(self):
sent = self.send(self.buffer)
self.buffer = self.buffer[sent:]
.. method:: handle_expt()
Called when there is out of band (OOB) data for a socket connection. This
will almost never happen, as OOB is tenuously supported and rarely used.
.. method:: handle_connect()
Called when the active opener's socket actually makes a connection. Might
send a "welcome" banner, or initiate a protocol negotiation with the
remote endpoint, for example.
.. method:: handle_close()
Called when the socket is closed.
.. method:: handle_error()
Called when an exception is raised and not otherwise handled. The default
version prints a condensed traceback.
.. method:: handle_accept()
Called on listening channels (passive openers) when a connection can be
established with a new remote endpoint that has issued a :meth:`connect`
call for the local endpoint. Deprecated in version 3.2; use
:meth:`handle_accepted` instead.
.. deprecated:: 3.2
.. method:: handle_accepted(sock, addr)
Called on listening channels (passive openers) when a connection has been
established with a new remote endpoint that has issued a :meth:`connect`
call for the local endpoint. *sock* is a *new* socket object usable to
send and receive data on the connection, and *addr* is the address
bound to the socket on the other end of the connection.
.. versionadded:: 3.2
.. method:: readable()
Called each time around the asynchronous loop to determine whether a
channel's socket should be added to the list on which read events can
occur. The default method simply returns ``True``, indicating that by
default, all channels will be interested in read events.
.. method:: writable()
Called each time around the asynchronous loop to determine whether a
channel's socket should be added to the list on which write events can
occur. The default method simply returns ``True``, indicating that by
default, all channels will be interested in write events.
In addition, each channel delegates or extends many of the socket methods.
Most of these are nearly identical to their socket partners.
.. method:: create_socket(family=socket.AF_INET, type=socket.SOCK_STREAM)
This is identical to the creation of a normal socket, and will use the
same options for creation. Refer to the :mod:`socket` documentation for
information on creating sockets.
.. versionchanged:: 3.3
*family* and *type* arguments can be omitted.
.. method:: connect(address)
As with the normal socket object, *address* is a tuple with the first
element the host to connect to, and the second the port number.
.. method:: send(data)
Send *data* to the remote end-point of the socket.
.. method:: recv(buffer_size)
Read at most *buffer_size* bytes from the socket's remote end-point. An
empty bytes object implies that the channel has been closed from the
other end.
Note that :meth:`recv` may raise :exc:`BlockingIOError` , even though
:func:`select.select` or :func:`select.poll` has reported the socket
ready for reading.
.. method:: listen(backlog)
Listen for connections made to the socket. The *backlog* argument
specifies the maximum number of queued connections and should be at least
1; the maximum value is system-dependent (usually 5).
.. method:: bind(address)
Bind the socket to *address*. The socket must not already be bound. (The
format of *address* depends on the address family --- refer to the
:mod:`socket` documentation for more information.) To mark
the socket as re-usable (setting the :const:`SO_REUSEADDR` option), call
the :class:`dispatcher` object's :meth:`set_reuse_addr` method.
.. method:: accept()
Accept a connection. The socket must be bound to an address and listening
for connections. The return value can be either ``None`` or a pair
``(conn, address)`` where *conn* is a *new* socket object usable to send
and receive data on the connection, and *address* is the address bound to
the socket on the other end of the connection.
When ``None`` is returned it means the connection didn't take place, in
which case the server should just ignore this event and keep listening
for further incoming connections.
.. method:: close()
Close the socket. All future operations on the socket object will fail.
The remote end-point will receive no more data (after queued data is
flushed). Sockets are automatically closed when they are
garbage-collected.
.. class:: dispatcher_with_send()
A :class:`dispatcher` subclass which adds simple buffered output capability,
useful for simple clients. For more sophisticated usage use
:class:`asynchat.async_chat`.
.. class:: file_dispatcher()
A file_dispatcher takes a file descriptor or :term:`file object` along
with an optional map argument and wraps it for use with the :c:func:`poll`
or :c:func:`loop` functions. If provided a file object or anything with a
:c:func:`fileno` method, that method will be called and passed to the
:class:`file_wrapper` constructor.
.. availability:: Unix.
.. class:: file_wrapper()
A file_wrapper takes an integer file descriptor and calls :func:`os.dup` to
duplicate the handle so that the original handle may be closed independently
of the file_wrapper. This class implements sufficient methods to emulate a
socket for use by the :class:`file_dispatcher` class.
.. availability:: Unix.
.. _asyncore-example-1:
asyncore Example basic HTTP client
----------------------------------
Here is a very basic HTTP client that uses the :class:`dispatcher` class to
implement its socket handling::
import asyncore
class HTTPClient(asyncore.dispatcher):
def __init__(self, host, path):
asyncore.dispatcher.__init__(self)
self.create_socket()
self.connect( (host, 80) )
self.buffer = bytes('GET %s HTTP/1.0\r\nHost: %s\r\n\r\n' %
(path, host), 'ascii')
def handle_connect(self):
pass
def handle_close(self):
self.close()
def handle_read(self):
print(self.recv(8192))
def writable(self):
return (len(self.buffer) > 0)
def handle_write(self):
sent = self.send(self.buffer)
self.buffer = self.buffer[sent:]
client = HTTPClient('www.python.org', '/')
asyncore.loop()
.. _asyncore-example-2:
asyncore Example basic echo server
----------------------------------
Here is a basic echo server that uses the :class:`dispatcher` class to accept
connections and dispatches the incoming connections to a handler::
import asyncore
class EchoHandler(asyncore.dispatcher_with_send):
def handle_read(self):
data = self.recv(8192)
if data:
self.send(data)
class EchoServer(asyncore.dispatcher):
def __init__(self, host, port):
asyncore.dispatcher.__init__(self)
self.create_socket()
self.set_reuse_addr()
self.bind((host, port))
self.listen(5)
def handle_accepted(self, sock, addr):
print('Incoming connection from %s' % repr(addr))
handler = EchoHandler(sock)
server = EchoServer('localhost', 8080)

:mod:`smtpd` --- SMTP Server
============================
.. module:: smtpd
:synopsis: A SMTP server implementation in Python.
.. moduleauthor:: Barry Warsaw <barry@python.org>
.. sectionauthor:: Moshe Zadka <moshez@moshez.org>
**Source code:** :source:`Lib/smtpd.py`
--------------
This module offers several classes to implement SMTP (email) servers.
.. deprecated:: 3.6
The `aiosmtpd <https://aiosmtpd.readthedocs.io/>`_ package is a recommended
replacement for this module. It is based on :mod:`asyncio` and provides a
more straightforward API.
Several server implementations are present; one is a generic
do-nothing implementation, which can be overridden, while the other two offer
specific mail-sending strategies.
Additionally the SMTPChannel may be extended to implement very specific
interaction behaviour with SMTP clients.
The code supports :RFC:`5321`, plus the :rfc:`1870` SIZE and :rfc:`6531`
SMTPUTF8 extensions.
SMTPServer Objects
------------------
.. class:: SMTPServer(localaddr, remoteaddr, data_size_limit=33554432,\
map=None, enable_SMTPUTF8=False, decode_data=False)
Create a new :class:`SMTPServer` object, which binds to local address
*localaddr*. It will treat *remoteaddr* as an upstream SMTP relayer. Both
*localaddr* and *remoteaddr* should be a :ref:`(host, port) <host_port>`
tuple. The object inherits from :class:`asyncore.dispatcher`, and so will
insert itself into :mod:`asyncore`'s event loop on instantiation.
*data_size_limit* specifies the maximum number of bytes that will be
accepted in a ``DATA`` command. A value of ``None`` or ``0`` means no
limit.
*map* is the socket map to use for connections (an initially empty
dictionary is a suitable value). If not specified the :mod:`asyncore`
global socket map is used.
*enable_SMTPUTF8* determines whether the ``SMTPUTF8`` extension (as defined
in :RFC:`6531`) should be enabled. The default is ``False``.
When ``True``, ``SMTPUTF8`` is accepted as a parameter to the ``MAIL``
command and when present is passed to :meth:`process_message` in the
``kwargs['mail_options']`` list. *decode_data* and *enable_SMTPUTF8*
cannot be set to ``True`` at the same time.
*decode_data* specifies whether the data portion of the SMTP transaction
should be decoded using UTF-8. When *decode_data* is ``False`` (the
default), the server advertises the ``8BITMIME``
extension (:rfc:`6152`), accepts the ``BODY=8BITMIME`` parameter to
the ``MAIL`` command, and when present passes it to :meth:`process_message`
in the ``kwargs['mail_options']`` list. *decode_data* and *enable_SMTPUTF8*
cannot be set to ``True`` at the same time.
.. method:: process_message(peer, mailfrom, rcpttos, data, **kwargs)
Raise a :exc:`NotImplementedError` exception. Override this in subclasses to
do something useful with this message. Whatever was passed in the
constructor as *remoteaddr* will be available as the :attr:`_remoteaddr`
attribute. *peer* is the remote host's address, *mailfrom* is the envelope
originator, *rcpttos* are the envelope recipients and *data* is a string
containing the contents of the e-mail (which should be in :rfc:`5321`
format).
If the *decode_data* constructor keyword is set to ``True``, the *data*
argument will be a unicode string. If it is set to ``False``, it
will be a bytes object.
*kwargs* is a dictionary containing additional information. It is empty
if ``decode_data=True`` was given as an init argument, otherwise
it contains the following keys:
*mail_options*:
a list of all received parameters to the ``MAIL``
command (the elements are uppercase strings; example:
``['BODY=8BITMIME', 'SMTPUTF8']``).
*rcpt_options*:
same as *mail_options* but for the ``RCPT`` command.
Currently no ``RCPT TO`` options are supported, so for now
this will always be an empty list.
Implementations of ``process_message`` should use the ``**kwargs``
signature to accept arbitrary keyword arguments, since future feature
enhancements may add keys to the kwargs dictionary.
Return ``None`` to request a normal ``250 Ok`` response; otherwise
return the desired response string in :RFC:`5321` format.
.. attribute:: channel_class
Override this in subclasses to use a custom :class:`SMTPChannel` for
managing SMTP clients.
.. versionadded:: 3.4
The *map* constructor argument.
.. versionchanged:: 3.5
*localaddr* and *remoteaddr* may now contain IPv6 addresses.
.. versionadded:: 3.5
The *decode_data* and *enable_SMTPUTF8* constructor parameters, and the
*kwargs* parameter to :meth:`process_message` when *decode_data* is
``False``.
.. versionchanged:: 3.6
*decode_data* is now ``False`` by default.
DebuggingServer Objects
-----------------------
.. class:: DebuggingServer(localaddr, remoteaddr)
Create a new debugging server. Arguments are as per :class:`SMTPServer`.
Messages will be discarded, and printed on stdout.
PureProxy Objects
-----------------
.. class:: PureProxy(localaddr, remoteaddr)
Create a new pure proxy server. Arguments are as per :class:`SMTPServer`.
Everything will be relayed to *remoteaddr*. Note that running this has a good
chance to make you into an open relay, so please be careful.
SMTPChannel Objects
-------------------
.. class:: SMTPChannel(server, conn, addr, data_size_limit=33554432,\
map=None, enable_SMTPUTF8=False, decode_data=False)
Create a new :class:`SMTPChannel` object which manages the communication
between the server and a single SMTP client.
*conn* and *addr* are as per the instance variables described below.
*data_size_limit* specifies the maximum number of bytes that will be
accepted in a ``DATA`` command. A value of ``None`` or ``0`` means no
limit.
*enable_SMTPUTF8* determines whether the ``SMTPUTF8`` extension (as defined
in :RFC:`6531`) should be enabled. The default is ``False``.
*decode_data* and *enable_SMTPUTF8* cannot be set to ``True`` at the same
time.
A dictionary can be specified in *map* to avoid using a global socket map.
*decode_data* specifies whether the data portion of the SMTP transaction
should be decoded using UTF-8. The default is ``False``.
*decode_data* and *enable_SMTPUTF8* cannot be set to ``True`` at the same
time.
To use a custom SMTPChannel implementation you need to override the
:attr:`SMTPServer.channel_class` of your :class:`SMTPServer`.
.. versionchanged:: 3.5
The *decode_data* and *enable_SMTPUTF8* parameters were added.
.. versionchanged:: 3.6
*decode_data* is now ``False`` by default.
The :class:`SMTPChannel` has the following instance variables:
.. attribute:: smtp_server
Holds the :class:`SMTPServer` that spawned this channel.
.. attribute:: conn
Holds the socket object connecting to the client.
.. attribute:: addr
Holds the address of the client, the second value returned by
:func:`socket.accept <socket.socket.accept>`
.. attribute:: received_lines
Holds a list of the line strings (decoded using UTF-8) received from
the client. The lines have their ``"\r\n"`` line ending translated to
``"\n"``.
.. attribute:: smtp_state
Holds the current state of the channel. This will be either
:attr:`COMMAND` initially and then :attr:`DATA` after the client sends
a "DATA" line.
.. attribute:: seen_greeting
Holds a string containing the greeting sent by the client in its "HELO".
.. attribute:: mailfrom
Holds a string containing the address identified in the "MAIL FROM:" line
from the client.
.. attribute:: rcpttos
Holds a list of strings containing the addresses identified in the
"RCPT TO:" lines from the client.
.. attribute:: received_data
Holds a string containing all of the data sent by the client during the
DATA state, up to but not including the terminating ``"\r\n.\r\n"``.
.. attribute:: fqdn
Holds the fully-qualified domain name of the server as returned by
:func:`socket.getfqdn`.
.. attribute:: peer
Holds the name of the client peer as returned by ``conn.getpeername()``
where ``conn`` is :attr:`conn`.
The :class:`SMTPChannel` operates by invoking methods named ``smtp_<command>``
upon reception of a command line from the client. Built into the base
:class:`SMTPChannel` class are methods for handling the following commands
(and responding to them appropriately):
======== ===================================================================
Command Action taken
======== ===================================================================
HELO Accepts the greeting from the client and stores it in
:attr:`seen_greeting`. Sets server to base command mode.
EHLO Accepts the greeting from the client and stores it in
:attr:`seen_greeting`. Sets server to extended command mode.
NOOP Takes no action.
QUIT Closes the connection cleanly.
MAIL Accepts the "MAIL FROM:" syntax and stores the supplied address as
:attr:`mailfrom`. In extended command mode, accepts the
:rfc:`1870` SIZE attribute and responds appropriately based on the
value of *data_size_limit*.
RCPT Accepts the "RCPT TO:" syntax and stores the supplied addresses in
the :attr:`rcpttos` list.
RSET Resets the :attr:`mailfrom`, :attr:`rcpttos`, and
:attr:`received_data`, but not the greeting.
DATA Sets the internal state to :attr:`DATA` and stores remaining lines
from the client in :attr:`received_data` until the terminator
``"\r\n.\r\n"`` is received.
HELP Returns minimal information on command syntax
VRFY Returns code 252 (the server doesn't know if the address is valid)
EXPN Reports that the command is not implemented.
