A BUGNOTE has been added to this bug. ====================================================================== http://dbmail.org/mantis/bug_view_advanced_page.php?bug_id=0000070 ====================================================================== Reported By: danweber Assigned To: aaron ====================================================================== Project: DBMail Bug ID: 70 Category: LMTP daemon Reproducibility: always Severity: major Priority: normal Status: assigned ====================================================================== Date Submitted: 23-Aug-04 01:43 CEST Last Modified: 26-Aug-04 06:08 CEST ====================================================================== Summary: Fails to give reponse upon completion of rcpt Description: A responce is needed directly after rcpt command. Otherwise its incompatible with the rfc, and it also makes python hang. I stumbled upon this when I was adding lmtp support for mailbox2dbmail. ======================================================================
---------------------------------------------------------------------- ilja - 23-Aug-04 13:32 CEST ---------------------------------------------------------------------- AFAIK the client _should_ support pipelining, which means the respons comes after the DATA command, not after every RCPT command. ---------------------------------------------------------------------- aaron - 23-Aug-04 18:11 CEST ---------------------------------------------------------------------- Actually, pipelining means that neither side should block or wait for anything during the RCPT stage. So both behaviors are slightly wrong. ---------------------------------------------------------------------- danweber - 24-Aug-04 18:50 CEST ---------------------------------------------------------------------- Its good practice to send a response after rcpt. This way it allows a compatible smtp client to be used with it, like python. Dan ---------------------------------------------------------------------- aaron - 24-Aug-04 19:28 CEST ---------------------------------------------------------------------- Oh, that's a good point. LMTP is a dialect of SMTP, the only difference is the HELO/EHLO/LHLO greeting. Simple scripts that speak simple SMTP can be easily modified to work with LMTP, but adding in the pipelining is more hassle than needed, since the particular behavior we are using isn't quite correct anyhow. So I agree we should change the responses to happen immediately following each RCPT. I'll post a patch this evening. ---------------------------------------------------------------------- aaron - 26-Aug-04 06:08 CEST ---------------------------------------------------------------------- This turns out to be fairly hard because I abstracted the list code out to a separate function, and so I'll need to un-abstract it a little bit. I'm still working on it, and expect to be done tomorrow evening. I'll commit the changes to HEAD and Ilja can patch it back to the release branch once we're 110% sure it's a correct patch.
