  Added test for behavior of operations on an unconnected SMTP object,
  and tests for NOOP, RSET, and VRFY. Corrected typo in a comment for
  testNonnumericPort. Added a check for constructing SMTP objects when
  non-numeric ports are included in the host name. Derived a server from
  SMTPServer to test various ESMTP/SMTP capabilities. Check that a
  second HELO to DebuggingServer returns an error. [GSoC - Alan McIntyre]

Python offers two different primitive operations based on regular expressions:
