    I"m suddenly having an unrouteable mail domain issue

    my etc/resolv.conf has:
    search serverdomain.com
    nameserver ##.###.##.###
    nameserver ##.###.##.###
    and http://www.dnsreport.com says dns is correct.


    I have ran
    /scripts/eximup --force
    /scripts/upcp --force
    /scripts/easyapache

    /etc/eximmailtrap does not exist
    /var/cpanel/cpanel.config is set to eximmailtrap=0

    /var/log/exim_mainlog
    shows me: R=fail_remote_domains: unrouteable mail domain "bellsouth.net"
    2006-09-17 19:46:03 1GP7Gt-0006NI-AD Frozen (delivery error message)

    which is root trying to mail me

    I have tried everything that has been suggested from posts from today back to 2003 without success. I'm at my wits end, I have three identical other servers and this ones mail just stopped working, and mail is what we do.

    Any suggestions?

    I'm running
    WHM 10.8.0 cPanel 10.9.0-C5
    CentOS 4.4 i686 - WHM X v3.1.0
    (Exim 4.52)

    Make sure that you do not have the following checked?
    - WHM > Tweak Settings > Prevent the user 'nobody' from sending out mail to remote addresses
    - Track the origin of messages sent though the mail server by adding the X-Sender headers (exim 4.34+ required)

    Then run these commands (in that order)
    /scripts/reseteximtodefaults
    /scripts/eximup --force
    /scripts/mailperm
    /scripts/fixvaliases
    /scripts/updateuserdomains

    Thank you for your help

    ok, i went into
    - WHM > Tweak Settings >

    and unchecked

    Prevent the user 'nobody' from sending out mail to remote addresses

    and unchecked

    - Track the origin of messages sent though the mail server by adding the X-Sender headers (exim 4.34+ required)

    although i have used these features successfully and continue to do so on three other servers.

    Then i ran these commands (in this order)
    /scripts/reseteximtodefaults
    /scripts/eximup --force
    /scripts/mailperm
    /scripts/fixvaliases
    /scripts/updateuserdomains


    Everything ran without error, and I emptied my mail que.
    I host several mail sites, so i didnt have to wait long for these bounced mails to start again.

    This message was created automatically by mail delivery software.

    A message that you sent could not be delivered to one or more of its
    recipients. This is a permanent error. The following address(es) failed:

    XXXXXXXXXX@126.com
    unrouteable mail domain "126.com"

    Same deal for root emails to me that should be going to gmail.com
    unrouteable mail domain "gmail.com"

    and others

    unrouteable mail domain "21cn.com"
    unrouteable mail domain "bellsouth.net"

    etc etc

    It does seem that regular mails are working now, the mails that arent being sent are via php scripts. (i had already deleted sendmail before one of my many attempts of /scripts/upcp --force)

    I'm running PHP Version 4.4.3
    './configure' '--prefix=/usr' '--with-xml' '--with-mm' '--enable-bcmath' '--enable-calendar' '--with-curl' '--enable-ftp' '--with-gd' '--with-jpeg-dir=/usr/local' '--with-png-dir=/usr' '--with-xpm-dir=/usr/X11R6' '--with-gettext' '--with-imap=/usr/local/imap-2004g' '--enable-mbstring' '--enable-mbstr-enc-trans' '--enable-mbregex' '--with-mcrypt' '--with-mhash' '--enable-magic-quotes' '--with-mm' '--with-mysqli' '--with-mysql=/usr' '--enable-discard-path' '--with-pear' '--enable-sockets' '--enable-track-vars' '--with-ttf' '--with-freetype-dir=/usr' '--enable-gd-native-ttf' '--with-zlib'

    Am I missing something that would make mails bounce with the "unroutable domain" errors?

    Can you telnet into the other servers from yours? That would help to show a resolver issue if there was one.

    Within Tweak Settings, "The maximum each domain can send out per hour (0 is unlimited):"

    Is this value set to anything else other than '0'...?
