Are you using SmartDNSHost in server.tab?
If so, is SmartDNSHost pointing to the same server that you had issued the
command:
dig embarqnow.net MX
?

Subject: [xmail] DbgFix: Mail loop detected
Just wanted to share a debug session to trace down a Mail loop
detected situation:
A bounce mail with reason Mail loop detected is generated under this
circumstance:
if it takes too many steps (operations) to get the first MX record
(or the final A record when MX is missing after trying all)
of the recipient domain than what is defined in server.tab under
MaxMTAOps 16
For example:
I had a mail to an address xx...@embarqnow.net and got that error
because that domain has many nameservers and a depth of 3 levels
to finally get the MX record, but the number of steps to get to the MX
exceeds the above defined 16 ...
