I have been looking at ways to have postfix talking to my twisted app and today tried LMTP successfully for the first time. What I've done so far is just subclass the ESMTP protocol and add do_LHLO which seems to do the trick for some basic usage at least. Looking at http://www.ietf.org/rfc/rfc2033.txt it seems like it shouldn't be to hard to make a proper LMTP implementation. Perhaps someone more familiar with twisted.mail could have a look.
Your mini LMTP implementation fails if a message is sent to several recipients, since LMTP must answer with a status code per destination. That is the main difference with SMTP.
But good starting point :)
Hope "somebody" takes the token and complete a RFC compliant implementation... :-p
Ok, I had a closer look and here's a more complete version, that sends a status code for each recipient. Try it out /Simon
class LMTP(smtp.ESMTP): def do_LHLO(self, rest): peer = self.transport.getPeer() try: host = peer.host except AttributeError: host = str(peer) self._helo = (rest, host) self._from = None self._to =  self.sendCode(250, '%s Hello %s, nice to meet you\n%s' % (self.host, host,self.listExtensions()))
def do_HELO(self,rest): return self.do_UNKNOWN(self,rest)
def do_EHLO(self,rest): return self.do_UNKNOWN(self,rest)
def _messageHandled(self, resultList): for (success, result) in resultList: if success: self.sendCode(250, 'OK') else: log.err(result) code = 550 msg = 'Could not deliver e-mail' smtperr = result.check(smtp.SMTPClientError) if smtperr: code = result.value.code msg = result.value.resp self.sendCode(code, msg)
