At it's core Lamson is just a really sweet wrapper around smtpd (http://docs.python.org/library/smtpd.html http://docs.python.org/library/smtpd.html) using asyncore for asynchronous socket IO. When a mail is received you can optionally process it and when done processing you can drop it on the floor (e.g. you're done with it) or you can send it to a 'relay' which means a IMAP or POP server (or really anything) if you so choose. I would generally say that yes, lamson is much more focused on receiving email via SMTP and doing [smart] processing on it.
