    There are some problems with the email server...
    Someone tried to send an email with multiple recipients in the Bcc field, but I got error messages like:

    "unrouteable mail domain ""

    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:

    Seemed to happen just after I enabled "Track the origin of messages sent though the mail server by adding the X-Source headers " which I initially had disabled but re-enabled to track some spammers down.

    Any work around aside disabling it again?

    I have Exim Dictionary ACL, Exim 4.5x, Cpanel 10.x, enabled "Include a list of Pop before SMTP senders in the X-PopBeforeSMTP header when relaying mail" and mailman.

    Any help appreciated.
