Installed ISPConfig3 on a CentOS VM using the Perfect Server Guide. Everything is up and running. I created a website and 2 email users. Since this is a test server it is using IP 10.0.0.11 and does not have a registered domain. I redirected root mail to User1 in /etc/aliases and that is working. Logwatch reports and RKhunter reports are being received by that user in SquirrelMail. The problem is that User1 and User2 cannot send or receive emails to/from each other. When I try to send an email it takes forever for the action to complete in the SquirrelMail webpage. It's like Squirrelmail cannot find Postfix. I do not see any obvious errors in the logs. Reinstalling and/or updating ISPConfig did not help. Any ideas?
Mailog Here are the contents of the mailog when I tried to send an email from [email protected] to [email protected] via Squirrelmail: Code: Mar 24 10:50:01 testserver pop3d: Connection, ip=[::ffff:127.0.0.1] Mar 24 10:50:01 testserver pop3d: Disconnected, ip=[::ffff:127.0.0.1] Mar 24 10:50:01 testserver postfix/smtpd[17924]: connect from localhost.localdomain[127.0.0.1] Mar 24 10:50:01 testserver postfix/smtpd[17924]: lost connection after CONNECT from localhost.localdomain[127.0.0.1] Mar 24 10:50:01 testserver postfix/smtpd[17924]: disconnect from localhost.localdomain[127.0.0.1] Mar 24 10:50:01 testserver imapd: Connection, ip=[::ffff:127.0.0.1] Mar 24 10:50:01 testserver imapd: Disconnected, ip=[::ffff:127.0.0.1], time=0 Mar 24 10:51:29 testserver imapd: Connection, ip=[::ffff:127.0.0.1] Mar 24 10:51:29 testserver imapd: LOGIN, [EMAIL="[email protected]"][email protected][/EMAIL], ip=[::ffff:127.0.0.1], port=[38758], protocol=IMAP Mar 24 10:51:29 testserver imapd: LOGOUT, [EMAIL="[email protected]"][email protected][/EMAIL], ip=[::ffff:127.0.0.1], headers=0, body=0, rcvd=30, sent=238, time=0 Mar 24 10:51:29 testserver imapd: Connection, ip=[::ffff:127.0.0.1] Mar 24 10:51:29 testserver imapd: LOGIN, [EMAIL="[email protected]"][email protected][/EMAIL], ip=[::ffff:127.0.0.1], port=[38759], protocol=IMAP Mar 24 10:51:29 testserver imapd: LOGOUT, [EMAIL="[email protected]"][email protected][/EMAIL], ip=[::ffff:127.0.0.1], headers=0, body=0, rcvd=485, sent=1654, time=0 Mar 24 10:51:30 testserver imapd: Connection, ip=[::ffff:127.0.0.1] Mar 24 10:51:30 testserver imapd: LOGIN, [EMAIL="[email protected]"][email protected][/EMAIL], ip=[::ffff:127.0.0.1], port=[38760], protocol=IMAP Mar 24 10:51:30 testserver imapd: LOGOUT, [EMAIL="[email protected]"][email protected][/EMAIL], ip=[::ffff:127.0.0.1], headers=0, body=0, rcvd=119, sent=900, time=0 Mar 24 10:52:58 testserver sendmail[18127]: o2OEqbZ0018127: Authentication-Warning: testserver.peachtest.com: apache set sender to [EMAIL="[email protected]"][email protected][/EMAIL] using -f Mar 24 10:52:58 testserver sendmail[18127]: o2OEqbZ0018127: [EMAIL="[email protected]"][email protected][/EMAIL], size=633, class=0, nrcpts=2, msgid=<[EMAIL="[email protected]"][email protected][/EMAIL]>, relay=apache@localhost Mar 24 10:52:58 testserver sendmail[18127]: o2OEqbZ0018127: [EMAIL="[email protected]"][email protected][/EMAIL], delay=00:00:21, mailer=esmtp, pri=60633, dsn=4.4.3, stat=queued Mar 24 10:52:58 testserver sendmail[18127]: o2OEqbZ0018127: [EMAIL="[email protected]"][email protected][/EMAIL], delay=00:00:21, mailer=esmtp, pri=60633, dsn=4.4.3, stat=queued Mar 24 10:52:58 testserver imapd: Connection, ip=[::ffff:127.0.0.1] Mar 24 10:52:58 testserver imapd: LOGIN, [EMAIL="[email protected]"][email protected][/EMAIL], ip=[::ffff:127.0.0.1], port=[38765], protocol=IMAP Mar 24 10:52:58 testserver imapd: LOGOUT, [EMAIL="[email protected]"][email protected][/EMAIL], ip=[::ffff:127.0.0.1], headers=0, body=0, rcvd=735, sent=203, time=0 UPDATE: All of the test emails I have sent are sitting in /var/spool/clientmqueue
Problem resolved I figured out the source of the problem: /etc/resolv.conf was misconfigured I had changed the domain name of my test server and forgot to update resolv.conf with the new domain name.
