Send Mail Connect Error
« on: July 25, 2022, 02:54:47 pm »
I am seeing this error when connecting from our server application.

Jul 25 13:47:28 zenserver postfix/smtpd[22265]: connect from unknown[10.10.1.3]
Jul 25 13:47:28 zenserver postfix/smtpd[22265]: lost connection after CONNECT from unknown[10.10.1.3]
Jul 25 13:47:28 zenserver postfix/smtpd[22265]: disconnect from unknown[10.10.1.3] commands=0/0

Connecting from thunderbird with same credentials is working ok.

Any one else seen this ?
Thanks

Hi,

Unfortunately, those messages are useless to identify the issue. Did you check the rest of the log file? And what about the log file '/var/log/mail.err'? or even the log file /var/log/syslog.

Thanks for reply,

mail.err is empty and syslog other than a bunch of samba errors contains this from thunderbird which is ok.

Jul 25 15:32:32 zenserver dovecot: imap-login: Login: user=<xxx@yyy.com>, method=PLAIN, rip=10.10.1.3, lip=10.10.1.38, mpid=3759, TLS, session=<CbzdDaLk29IKCgED>

and in syslog same error as mail log from my client.

Jul 25 15:36:34 zenserver postfix/smtpd[3996]: connect from paulwin7.youdo.local[10.10.1.3]

and when thunderbird send mail from mailog.

This is an authorisation issue  from our side rather not a problem with zentyal. Sorry for confusion.
