Good Day All, Can anyone take a look at my mail log below and point me in the right direction please? I know I have missed something! I need help troubleshooting no email internally or externally. What additional information do I need to provide? I built the system following this HowTo: http://www.howtoforge.org/perfect-server-centos-5.2-ispconfig-3 I followed everything in this HowTo except I built postfix from postfix-2.3.3-2.1.mysql_pgsql.src.rpm. Could not find the Postfix file in the tutorial. Maybe this is the issue?? I have checked and rechecked my config files and I am lost ;-( "Dec 4 16:31:56 kd8q postfix/qmgr[14576]: 5CA3D2F6885: from=, size=498, nrcpt=1 (queue active) Dec 4 16:32:06 kd8q postfix/smtp[18572]: 5CA3D2F6885: to=, relay=none, delay=7553, delays=7543/0.12/10/0, dsn=4.4.3, status=deferred (Host or domain name not found.

Check that the nameservers that are listed in /etc/resolv.conf are reachable from your server and that they are working.
Thanks for the reply Till! DNS resolves as the website is up.

OK. Got the MX record problem resolved. Now the connection is refused on port 25 of the server?? Is this an ISPConfig 3 configuration problem? Checked my router ports and is being forwarded to the server.
BTW...I can connect to port 25 via localhost and postfix queues mail but it does not seem to go anywhere??
What are the outputs of Code: netstat -tap , Code: iptables -L , and Code: postqueue -p ? Also make sure that your ISP doesn't block port 25.
Hello Falco, THanks so much for your help! Here you go... Ohh, and the port is open to the server. I can now telnet into port 25
Hello Falco, Here is resolv.conf [root@kd8q etc]# cat /etc/resolv.conf search kd8q.com nameserver 192.168.1.1
Ok, now we are getting somewhere. I corrected resolv.conf by adding ISP's nameserver. Now i can send mail but not recieve. Here is the error in the mail error log: Dec 7 19:07:38 kd8q postfix/smtpd[24244]: NOQUEUE: reject: RCPT from cpe-184-57-213-175.cinci.res.rr.com[184.57.213.175]: 550 5.1.1 : Recipient address rejected: User unknown in local recipient table; from= to= proto=SMTP helo= Here is an error from Squrrillmail: Dec 7 19:07:38 kd8q postfix/smtpd[24244]: NOQUEUE: reject: RCPT from cpe-184-57-213-175.cinci.res.rr.com[184.57.213.175]: 550 5.1.1 : Recipient address rejected: User unknown in local recipient table; from= to= proto=SMTP helo= And here is an error from Outlook Express: The message could not be sent because one of the recipients was rejected by the server.

Does that sound resonable? How do I troubleshoot? Thanks!
Oooops, Here is the error from SquirrelmailThe above is a dup of mail error log) Email delivery error Server replied: 67 Can't execute command '/usr/sbin/sendmail -i -t [email protected]'.
Hi Till! Here you go root@kd8q web3]# ls -la /usr/sbin/sendmail lrwxrwxrwx 1 root root 21 Nov 26 11:50 /usr/sbin/sendmail -> /etc/alternatives/mta [root@kd8q Thanks for your help!
Ok, and now: ls -la /etc/alternatives/mta If it points to another symlink, then post the ls -la for the target too.
Ok Till, here you go! root@kd8q web3]# ls -la /etc/alternatives/mta lrwxrwxrwx 1 root root 27 Nov 26 15:53 /etc/alternatives/mta -> /usr/sbin/sendmail.sendmail root@kd8q web3]# ls -la /usr/sbin/sendmail.sendmail -rwxr-sr-x 1 root smmsp 806460 Mar 31 2010 /usr/sbin/sendmail.sendmail That's where the trail ends! Thanks again for your help
Does /usr/sbin/sendmail.postfix exist? Do you use Postfix? If so, you can change the symlink as follows: Code: ln -sf /usr/sbin/sendmail.postfix /etc/alternatives/mta
Thanks for everything Falco! I had too many issues on the Centos installation so I started over with Debian Lenny ;-) I hated to give up but since IspConfig3 was built on Debian, I figured I would have better success with that!
