I accidentally blocked port 25 using the firewall for a few hours, and now I have problems receiving mail. I am using pop3 with a maildir. For all the logs, everything seems to be working ok , but I only get a few mails out of all the mails i should get. I can't understand it as i did not really change any configs. SMTP works fine:- Feb 6 21:51:24 server1 postfix/smtpd[11353]: connect from 85-18-136-77.fastres.net[85.18.136.77] Feb 6 21:51:24 server1 postfix/smtpd[11353]: setting up TLS connection from 85-18-136-77.fastres.net[85.18.136.77] Feb 6 21:51:27 server1 postfix/smtpd[11353]: TLS connection established from 85-18-136-77.fastres.net[85.18.136.77]: TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits) Feb 6 21:51:27 server1 postfix/smtpd[11353]: 64C506F566E: client=85-18-136-77.fastres.net[85.18.136.77], sasl_method=PLAIN, sasl_username=web1_info Feb 6 21:51:27 server1 postfix/cleanup[11626]: 64C506F566E: message-id=<1202331085.19281.0.camel@samsung-x65> Feb 6 21:51:27 server1 postfix/qmgr[10433]: 64C506F566E: from=<[email protected]>, size=662, nrcpt=1 (queue active) Feb 6 21:51:27 server1 postfix/smtp[11656]: 64C506F566E: to=<[email protected]>, relay=smtp.tin.it[62.211.72.32]:25, delay=0.5, delays=0.3/0.01/0.11/0.09, dsn=2.0.0, status=sent (250 <47AA15A60002DB3F> Mail accepted) Feb 6 21:51:27 server1 postfix/qmgr[10433]: 64C506F566E: removed Feb 6 21:51:28 server1 postfix/smtpd[11353]: disconnect from 85-18-136-77.fastres.net[85.18.136.77] here is what i see when i send myself a mail from another mailbox:- Feb 6 21:55:41 server1 postfix/smtpd[11715]: BFD3B6F4001: client=smtp1web.tin.it[212.216.176.195] Feb 6 21:55:41 server1 postfix/cleanup[11757]: BFD3B6F4001: message-id=<[email protected]> Feb 6 21:55:41 server1 postfix/qmgr[10433]: BFD3B6F4001: from=<[email protected]>, size=724, nrcpt=1 (queue active) Feb 6 21:55:41 server1 postfix/pickup[10432]: D2F026F56BF: uid=10003 from=<web1_showe> Feb 6 21:55:41 server1 postfix/cleanup[11757]: D2F026F56BF: message-id=<[email protected]> Feb 6 21:55:41 server1 postfix/local[11758]: BFD3B6F4001: to=<[email protected]>, orig_to=<[email protected]>, relay=local, delay=0.64, delays=0.6/0/0/0.04, dsn=2.0.0, status=sent (delivered to command: /usr/bin/procmail -f-) Feb 6 21:55:41 server1 postfix/qmgr[10433]: BFD3B6F4001: removed When i go to get the message with my client, i am prompted for the certificate okay, but no message arrives.
