    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?

    port 25 is ok. I did a quick check from dnsstuff and got the following reponse.

    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

    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.

    What's the output of
    Code:
    dig MX  bookowl.co.uk
    on your server? What's in /etc/resolv.conf?

    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.

    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.

    Please change it to
    Code:
    nameserver 145.253.2.75
    nameserver 193.174.32.18
    Also, make sure that SELinux is disabled.
