Everything was working fine,until over the weekend. I can send emails without a problem but I have a problem receiving them. I also am unable to telnet bookowl.co.uk I get connection refused. But if I telnet the ip address 192.168.*.* then I can do a ehlo and everything seems fine. I can also telnet from my laptop and both the domain name and ip are accepted. The hosts file looks ok 127.0.0.1 localhost.localdomain There are no errors showing in the maillog file except that when I log on there is a delay of around 6 mins before a message is placed on the lmaillog saying that I have been disconnected because of inactivity.
I assume you use port forwarding on your router? Did your ISP do some work this weekend to block traffic over port 25?
UPDATE: The reason for the 6 minute delay turned out to be 91700 emails in the bookowl.co.uk mailfolder cur I have deleted these and now the delay has disapeared. I also had thousands of emails on Sunday morning which caused a lock up on my server. The email seem to be system emails. If I get another I will post a copy of it I am still unable to telnet bookowl.co.uk from the server although I can from my laptop. Port 25 is open Also I have noticed an error message 'Bind to port 22 on 0.0.0.0 failed' which I believe is something to do with ipv6/ipv4 Anybody know what is happening Thanks
It's a DNS problem. bookowl.co.uk doesn't exist in DNS: Code: mh1:~# telnet bookowl.co.uk 25 telnet: could not resolve bookowl.co.uk/25: No address associated with hostname mh1:~# dig bookowl.co.uk ; <<>> DiG 9.2.1 <<>> bookowl.co.uk ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 64517 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;bookowl.co.uk.

Errrm, the MX record points to mail1.bookowl.co.uk and telnet-ting to that server works.

I'm getting different results. Maybe he has changed it recently and the modifications haven't fully propagated yet?
Since deleting the emails I am now able to send and receive emails. I think the problem was the amount of emails I had was causing a timeout on my system. I think the problem originated because I am unable to receive admin emails and possibly the ipv6 issue. I also am still unable to telnet bookowl.co.uk 25 from my server, although I can from my laptop connected to the network.

That's because you need to specify a valid user for root in your aliases file. root is now directed to the domain in /etc/aliases. Code: # Person who should get root's mail root: bookowl.co.uk-andrew should be something like: Code: # Person who should get root's mail root: [email protected] Don't forget to run 'newaliases' after making changes.
Thanks martinfst I made the changes in the aliases file and run newaliases also rebooted system. I still get errors in the maillog and the mail not forwarded. I did a flush to try and force it through but nothing. maillog Code: Feb 8 11:55:25 server1 sendmail[2799]: alias database /etc/aliases rebuilt by root Feb 8 11:55:25 server1 sendmail[2799]: /etc/aliases: 77 aliases, longest 20 bytes, 789 bytes total Feb 8 11:55:39 server1 dovecot: pop3-login: Login: user=<bookowl.co.uk-andrew>, method=PLAIN, rip=::ffff:192.168.16.80, lip=::ffff:192.168.16.90 Feb 8 11:55:39 server1 dovecot: POP3(bookowl.co.uk-andrew): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 Feb 8 11:55:46 server1 postfix/qmgr[2428]: 19CC091E30C: from=<[email protected]>, size=1221, nrcpt=1 (queue active) Feb 8 11:55:46 server1 postfix/qmgr[2428]: 0E38291E30A: from=<[email protected]>, size=30420, nrcpt=1 (queue active) Feb 8 11:55:47 server1 postfix/smtp[2810]: connect to server1.elmtreedesign.co.uk[194.106.43.87]: Connection refused (port 25) Feb 8 11:55:47 server1 postfix/smtp[2812]: connect to server1.elmtreedesign.co.uk[194.106.43.87]: Connection refused (port 25) Feb 8 11:55:47 server1 postfix/smtp[2810]: 19CC091E30C: to=<[email protected]>, relay=none, delay=28286, status=deferred (connect to server1.elmtreedesign.co.uk[194.106.43.87]: Connection refused) Feb 8 11:55:47 server1 postfix/smtp[2812]: 0E38291E30A: to=<[email protected]>, relay=none, delay=28394, status=deferred (connect to server1.elmtreedesign.co.uk[194.106.43.87]: Connection refused)
Are 'bookowl.co.uk' and 'server1.elmtreedesign.co.uk' on the same server? If yes, have a look at '/etc/postfix/local-host-names'. It should contain both domains/servers.
Thanks Till and martinfst Both domains are on the same server and are list in local-host-names Code: ################################### # # ISPConfig local-host-names Configuration File # Version 1.0 # ################################### localhost server1.elmtreedesign.co.uk localhost.server1.elmtreedesign.co.uk localhost.elmtreedesign.co.uk localhost.localdomain www.bookowl.co.uk www.royalspring.co.uk bookowl.co.uk #### MAKE MANUAL ENTRIES BELOW THIS LINE! #### The output of netstat is Code: ################################### # # ISPConfig local-host-names Configuration File # Version 1.0 # ################################### localhost server1.elmtreedesign.co.uk localhost.server1.elmtreedesign.co.uk localhost.elmtreedesign.co.uk localhost.localdomain www.bookowl.co.uk www.royalspring.co.uk bookowl.co.uk #### MAKE MANUAL ENTRIES BELOW THIS LINE! #### and the output of iptables is Code: [root@server1 ~]# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination [root@server1 ~]# Thanks for your help

Please change it to Code: nameserver 145.253.2.75 nameserver 193.174.32.18 Also, make sure that SELinux is disabled.
Thanks Falko Have changed the nameservers. will have to wait till saturday to see if the emails come through, allthough I have tried to flush the old ones with no luck.
