Postfix - mail server connects and then disconnects

Question

I have problems receiving mails from my security cam

My mailserver is running postfix and dovecot

By checking /var/log/mail.log the output is this

The cam's settings is set to

SMTP Server Port = 25
Secure SSL = No

Sender mail address = <My mail address>
Receiver mail address = <My mail address (for testing)>
Subject = Alarm from Y-Cam
Message = Testing

according to your session log, postfix does not offer AUTH capability after EHLO, that's probably why your cam QUIT's immediately since it is configured to do SMTP authentication.

Make sure your postfix sasl auth configuration works without the cam first, check dovecot logs as well.

Looks like your client asks to QUIT immediately after the EHLO response:

mail postfix/smtpd[1677]: > §.tdc.net[§]: 250 DSN
mail postfix/smtpd[1677]: watchdog_pat: 0xb84c9470
mail postfix/smtpd[1677]: < §.tdc.net[§]: QUIT
mail postfix/smtpd[1677]: > §.tdc.net[§]: 221 2.0.0 Bye

In fact the only input from the client is EHLO localhost then QUIT.

No surprise, postfix is obliging :).

What is watchdog_pat? As I think it maybe comes from there. And I will add the settings from the cam in about a minute – The87Boy Mar 20 '13 at 21:46
