Hi there again... I have a problem (I guess) with the mailserver in my ISPconfig3 installation, meaning that I can send email but I cannot receive. According to MXTOOLBOX.COM everything is fine with the DNS and I receive email sent via telnet directly to the SMTP server. The DNS was added days ago and I can exclude propagation delays. I disabled the spamfilter and the receiving is enabled. This is an excerpt from the mail log: Code: Sep 11 14:35:02 ts101485 pop3d: Connection, ip=[::1] Sep 11 14:35:02 ts101485 pop3d: Disconnected, ip=[::1] Sep 11 14:35:02 ts101485 imapd: Connection, ip=[::1] Sep 11 14:35:02 ts101485 imapd: Disconnected, ip=[::1], time=0 Sep 11 14:35:02 ts101485 postfix/smtpd[5893]: connect from localhost[::1] Sep 11 14:35:02 ts101485 postfix/smtpd[5893]: lost connection after CONNECT from localhost[::1] Sep 11 14:35:02 ts101485 postfix/smtpd[5893]: disconnect from localhost[::1] Sep 11 14:36:41 ts101485 imapd: Connection, ip=[::1] Sep 11 14:36:41 ts101485 imapd: LOGIN, [email protected], ip=[::1], port=[52322], protocol=IMAP Sep 11 14:36:41 ts101485 imapd: LOGOUT, [email protected], ip=[::1], headers=0, body=0, rcvd=119, sent=900, time=0 Sep 11 14:36:41 ts101485 imapd: Connection, ip=[::1] Sep 11 14:36:41 ts101485 imapd: LOGIN, [email protected], ip=[::1], port=[52323], protocol=IMAP Sep 11 14:36:41 ts101485 imapd: LOGOUT, [email protected], ip=[::1], headers=0, body=0, rcvd=87, sent=391, time=0 Sep 11 14:40:02 ts101485 imapd: Connection, ip=[::1] Sep 11 14:40:02 ts101485 pop3d: Connection, ip=[::1] Sep 11 14:40:02 ts101485 pop3d: Disconnected, ip=[::1] Sep 11 14:40:02 ts101485 imapd: Disconnected, ip=[::1], time=0 Sep 11 14:40:02 ts101485 postfix/smtpd[6068]: connect from localhost[::1] Sep 11 14:40:02 ts101485 postfix/smtpd[6068]: lost connection after CONNECT from localhost[::1] Sep 11 14:40:02 ts101485 postfix/smtpd[6068]: disconnect from localhost[::1] Sep 11 14:41:42 ts101485 imapd: Connection, ip=[::1] Sep 11 14:41:42 ts101485 imapd: LOGIN, [email protected], ip=[::1], port=[52331], protocol=IMAP Sep 11 14:41:42 ts101485 imapd: LOGOUT, [email protected], ip=[::1], headers=0, body=0, rcvd=87, sent=391, time=0 Sep 11 14:41:57 ts101485 clamd[30146]: SelfCheck: Database status OK.

It looks like the problem was related to DNS anyway. I received all the emails as soon as I resolved this: http://www.howtoforge.com/forums/showthread.php?t=58685
