    Hello,

    I need a little help with my postfix mailserver.
    (system: suse 10.1 (perfect setup) and ispconfig)

    Everything seems to be working basically. I have registered few webs and created an email account for one of them.
    I can connect to the account with Thunderbird seemingly, but the test mail just doesn't get there. The sending looks completely normal, no error reports by Thunderbird.

    I have looked through a lot of mail-concerning forum posts, but nothing seems to fit/work for me (can it be I don't have a /var/log/mail.log ?).
    After sending a mail the new, tmp and cur directories in Maildir are still empty.
    (yes the Maildir option is active)

    Any ideas?

    Thank you,
    regards, Tom

    Update:

    I find that the problem is a bind / nameserver problem. I had deactivated my bind for I didn't want to use it for the pages I host. When I activated it for trial suddenly the mailserver worked.
    Is it really necessary to activate bind for postfix?
    Or have I made a mistake registering the nameserver entries at my providers nameserver? What must be written in the zonefile for postfix to work correctly?

    Regards, Tom

    Are there any external nameservers listed in /etc/resolv.conf thet where reachable from your server?

    Yes, there are four, and -ooops- one of them was the nameserver I tried to set up on my server and which is now disabled. But the other three are ok, so I removed the one entry and restarted the network, but that didn't help.

    It's like that now:
    - Bind service disabled.
    I can send mails to the test account and read them via Thunderbird, but can not send mails.

    The following is added to /var/log/main.info, when I try to send mail:
    Nov 26 16:22:23 whitespace postfix/smtp[8277]: 7BECB844ED: to=<XXXXXX@web.de>, relay=none, delay=1924, status=deferred (Host or domain name not found. Name service error for name=web.de type=MX: Host not found, try again)

    As far as I understand it, my server can't resolve the target address in the mail. But why is that?
    The nameserver entry at my provider's nameserver is:

    $TTL 86400
    @ IN SOA ns1.first-ns.de. postmaster.robot.first-ns.de. (
    2006112300 ; serial
    14400 ; refresh
    1800 ; retry
    604800 ; expire
    86400 ) ; minimum

    @ IN NS robotns3.second-ns.com.
    @ IN NS robotns2.second-ns.de.
    @ IN NS ns1.first-ns.de.

    @ IN A here.is.my.IP
    localhost IN A 127.0.0.1
    mail IN A here.is.my.IP
    www IN A here.is.my.IP
    ftp IN CNAME www
    imap IN CNAME www
    loopback IN CNAME localhost
    pop IN CNAME www
    relay IN CNAME www
    smtp IN CNAME www
    @ IN MX 10 mail


    Thank you,

    What's in /etc/resolv.conf?

    The resolv.conf looks like that:

    domain mydomainname.de

    nameserver 213.239.242.238
    nameserver 213.133.105.6
    nameserver 193.47.99.3

    Can you try this in /etc/resolv.conf instead?
    Code:
    nameserver 145.253.2.75
    nameserver 193.174.32.18
    nameserver 194.25.0.60
    Also, what's the output of
    Code:
    updatedb
    locate resolv.conf
    ?
