    Sending mails on Intranet/locally on the same PC without problem.


    2)
    All mails sent on yahoo.com/gmail.com to this server returned saying users NOT found. However the respective users including Maildir have been created. Mails sent to them on Intranet w/o problem.

    Please advise where shall I check? TIA

    Hi folks,

    Problem half solved.

    Now I can send mails to yahoo.com after running;

    $ sudo touch /etc/postfix/virtusertable
    $ sudo postmap /etc/postfix/virtusertable
    $ sudo /etc/init.d/postfix restart


    But still can't receive mail. Mails sent on yahoo.com to users on this server returned immediately saying users NOT found..


    $ cat /etc/postfix/virtusertable
    No printout. It is empty.


    $ ls -l /etc/postfix/ | grep virtusertable
    Code:
    -rw-r--r-- 1 root root     0 2007-10-31 21:58 virtusertable
    -rw-r--r-- 1 root root 12288 2007-10-31 21:58 virtusertable.db
    

    $ sudo tail /var/log/mail.log

    Please make sure that the MX record for your domain points to the correct server. You can check with
    Code:
    dig mx yourdomain.com

    The mails go to smtp.secureserver.net because it has the highest priority, and I guess that server doesn't know your users. Change the MX record so that only ubuntu.satimis.com is left as your MX.

    On MX (Mail Exchange):-

    Delete;
    smtp.secureserver.net
    mailstore1.secureserver.net

    leaving only;
    ubuntu.satimis.com


    Sent one mail to 4 users;
    satimis
    fmaster
    administrator
    newuser

    The mail has not been returned. But it never arrived.

    satimis
    fmaster
    administrator
    All have Maildir directory.

    Only newuser, a new user, is without Maildir. The trick is here. Maildir will be automatically created if the 1st new mail arrives.

    Now where has the mail gone ???



    Edit:

    Mail returned

    This might be a temporary problem. It can take up to 72 hours until DNS changes propagate.

    There are no DNS records for that domain; there's not even an authoritative DNS server:

    Is it possible that your domain expired because you forgot to renew it?

    Hi Maximus_DDT,


    I solved my problem only playing around on the Registrar's Total DNS Control Panel. Please recheck yours on your registrar's website

    :( still no solved

    The domain was renew. I chek it twice.

    This is the main.cf file on my server. The registered domain is on www.nic.com.mx.

    When I installed the mail server, the main domain is mail.cf.com.mx. Actually, the other alias to genes.com.mx are functional, then when I used [B][email protected][/B] send me the error, but when I used [B][email protected][/B] IT WORKS!!

    Its a problem with the server or with my internet provider?? :S

    Strange. Now there's an MX record, but no A record and no name servers:

    Apologize...

    I'm very sorry.... I delay so much to comment my situation with the problem.:(

    I really appreciate all the comments and "tips", and its very embarrassing to me, but the solution was very dramatic, because my accountant was the responsible of this situation. The DNS was paid on time, but the person on charge to make the payment delayed several days. All the mails are functionally. The mail server its working fine.

    I was very mad with that person, and feel so anger.

    thanks a lot for the help. I know that in this place I can learn more about linux affairs.

    Thanks Again!!:D
