SMTP service loops and message not sent

Postby schnee » Fri Mar 19, 2010 10:52 pm

Hi,

I'M using MailEnable on a server with several applications sending messages to members.
I'm experiencing some weird problem.
Depending on the content of the message, sometimes, the server loops and repeat the same action for more than 100 000 times !
And the message is not even delivered.
Here are the lines I find in te Activity logs:
03/19/10 18:33:00 SMTP-IN D6AE7B2403654928B8A34799212A81C4.MAI 996 127.0.0.1 220 mail.internetique.com ESMTP MailEnable Service, Version: 3.62-- ready at 03/19/10 18:33:00 0 0
03/19/10 18:33:00 SMTP-IN D6AE7B2403654928B8A34799212A81C4.MAI 996 127.0.0.1 HELO HELO 174.142.68.186 250 Requested mail action okay, completed 43 21

03/19/10 18:33:00 SMTP-IN D6AE7B2403654928B8A34799212A81C4.MAI 996 127.0.0.1 RCPT RCPT TO: <schneegans@internetique.com> 250 Requested mail action okay, completed 43 40
03/19/10 18:33:00 SMTP-IN D6AE7B2403654928B8A34799212A81C4.MAI 996 127.0.0.1 DATA DATA 354 Start mail input; end with <CRLF>.<CRLF> 46 6

Repeted at nauseam. Only the .MAI file name is changed.
Looks like a QUIT command is missing.
I noticed that it happens mostly when message ends with some blank lines, but not always.
Messages are sent multipart, with both text and HTML parts.

Any idea?

I would look at whether the application is getting the ok from mailenable that it is expecting.
Otherwise it assumes the message failed and does it again.
I have my security set so such confirmations are never given to keep spammers guessing.
