'''SMTP/ESMTP client class.

This should follow RFC 821 (SMTP), RFC 1869 (ESMTP), RFC 2554 (SMTP
Authentication) and RFC 2487 (Secure SMTP over TLS).

Notes:

Please remember, when doing ESMTP, that the names of the SMTP service
extensions are NOT the same thing as the option keywords for the RCPT
and MAIL commands!

Example:

>>> import smtplib
  >>> s=smtplib.SMTP("localhost")
  >>> print s.help()
  This is Sendmail version 8.8.4
  Topics:
      HELO    EHLO    MAIL    RCPT    DATA
      RSET    NOOP    QUIT    HELP    VRFY
      EXPN    VERB    ETRN    DSN
  For more info use "HELP <topic>".
  To report bugs in the implementation send email to
      sendmail-bugs@sendmail.org.
  For local information send email to Postmaster at your site.
  End of HELP info
  >>> s.putcmd("vrfy","someone@here")
  >>> s.getreply()
  (250, "Somebody OverHere <somebody@here.my.org>")
  >>> s.quit()

This method may raise the following exceptions:

SMTPHeloError          The server didn't reply properly to
                                the helo greeting.

                                error code (other than a refusal of
                                a recipient).

Note: the connection will be open even after an exception is raised.

Example:

>>> import smtplib
         >>> s=smtplib.SMTP("localhost")
         >>> tolist=["one@one.org","two@two.org","three@three.org","four@four.org"]

         { "three@three.org" : ( 550 ,"User unknown" ) }
         >>> s.quit()

In the above example, the message was accepted for delivery to three
        of the four addresses, and one was rejected, with the error code
        550.  If all addresses are accepted, then the method will return an
