[cobalt-users] 554 ... Local configuration error behind firewall

["Mike Aus" <maus@xxxxxxxxxxxx>]

Anyone else encounter this?

We recently moved our RaQ3 (mail and dns server) behind a firewall with nat.
I have no problem sending or receiving emails from outside our network, but
whenever an email is sent between two cobalt users, the following message is
sent from the mailer daemon to the postmaster:


   ----- The following addresses had permanent fatal errors -----
<jharris@xxxxxxxxxxxx>

   ----- Transcript of session follows -----
554 MX list for bid4real.com. points back to cobalt.bid4real.com
554 <jharris@xxxxxxxxxxxx>... Local configuration error


The sendmail.cw and DNS entries appear OK.  Could this be a problem with
nat?  The cobalt has different external and internal ips.
