Hello everyone,

Has anyone seen this error message before with managed google apps email to
bellsouth email addresses?

======================
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:

      <recipient>@bellsouth.net
        host ff-ip4-mx-vip1.prodigy.net [144.160.159.21]
        SMTP error from remote mail server after MAIL FROM:

    Action: failed

I plan to the abuse email to see if I can get further details but just
wondering if anyone has seen it before.
