    Hi,

    We have a FreeBSD 4.7 server on which Cpanel (CURRENT 10.2.0-c89) is ruunning. Mail server is Exim version 4.51. We are facing a weired mail issue on our server. Our server won't accept any mails from certain domains. Please note the following log; when we tried to send a mail to our server from another server.
    ---------------------------------------------------------------------------------------------------
    mail -v test@domain.com
    Subject: Test
    Test mail from admin
    Cc:
    LOG: MAIN
    cwd=/root 4 args: send-mail -i -v test@domain.com
    LOG: MAIN
    <= root@x.otherdomain.com U=root P=local S=346 T="Test"
    root@one [~]# LOG: MAIN
    cwd=/var/spool/exim 4 args: /usr/sbin/exim -v -Mc 1Dg0sA-00011K-Ua
    delivering 1Dg0sA-00011K-Ua
    LOG: retry_defer MAIN
    == test@domain.com R=lookuphost T=remote_smtp defer (-53): retry time not reached for any host

    -----------------------------------------------------------------------------------------------------

    We are also getting panic logs in /var/log/messages as shown below.

    Jun 8 06:41:09 home /kernel: pid 84328 (exim-4.51-0), uid 26: exited on signal 11
    Jun 8 06:41:09 home /kernel: pid 84329 (exim-4.51-0), uid 26: exited on signal 11
    Jun 8 06:41:10 home /kernel: pid 84330 (exim-4.51-0), uid 26: exited on signal 11
    Jun 8 06:41:15 home /kernel: pid 84331 (exim-4.51-0), uid 26: exited on signal 11
    Jun 8 06:41:49 home /kernel: pid 84344 (exim-4.51-0), uid 26: exited on signal 11
    Jun 8 06:44:36 home /kernel: pid 84408 (exim-4.51-0), uid 26: exited on signal 11

    Any help will be appreciated.

    Install fresh copy of Exim on your server. Double check on the DNS and NSs and make sure they are configured properly. I could be wrong, but sig 11 could be: a sign of a bad hardware, or memory problem.

    Thanks for looking into it Andy.. I had already reinstall the Exim.( /scripts/updatenow &&
    /scripts/eximup --force). But still no luck :-(

    Those panic messages will stop when we stop the named. Any idea ???

    As I said, you need to double check on your DNS and zones. Running a couple of commands won't fix the problem, sometimes. If you run out of ideas, hire a sys admin. We can help.

    Go on, have a guess
    Yes, it's usually either a DNS issue, or they're falling foul of sender verification if you have that enabled.

    Hi Chirpy thanks for looking into it. We have double checked the DNS entries. It resoves fine from both inside and outside the server. I forgot to mention one thing that this server accepts mail from yahoo and gmail. But fails to accepts from certaine servers. This is the error that we get when we send mail from another server.

    Another thing to check is whether you have a reverse DNS PTR entry for your servers main IP address. That is, if you run the following substituting in your IP address, do you get a response other than just an SOA entry:

    dig -x 11.22.33.44
