At any rate, what it looks like to us is that customers using Bell
SMB outbound mail servers, possibly other outbound mail servers on
Bell (Nexxia, Sympatico?) to destination domains whose NS are hosted
on our nameservers seem to have the MX record *ignored* and the mail
is delivered to the A record for the domain.
We also suspect that it happens when the MX record points at a host
back inside the Bell network/address space.
I had a quick look on our web server for the last 7 days (where the A
record for sentex.net resides), and the only hosts contacting us
there trying to send from @sympatico email are from Hotmail IP space
(Bell I think outsources their resi email to MSN/Hotmail). What IP
addresses are involved in your case ? Send them to me and I can take
a look to see if they are showing up. If you need more detail (SMTP
IDs etc) let me know and I can send that offlist.
