A quick one ... ?
... mail is being rejected from one of my clients to one of their partners
because their mail server is claiming that the sending machine's dns doesn't
resolve. We aren't authoritative (in the Internet sense ;-) for our subnet
for our ISP, so we can't easily make it resolve if they're doing reverse DNS
and checking the host names (which I've seen some mail server software, like
Imail, do). Logs:

The primary mail server there is running groupwise ...
"220 wwd.von.ca GroupWise Internet Agent 5.5.1 Ready (C)1993, 1998 Novell,
Inc."
... which is the one rejecting our mail, but their secondary is running
sendmail:
"220 queue1.magma.ca ESMTP Sendmail 8.9.3/8.9.3; Thu, 31 Aug 2000
15:11:03 -0400 (EDT)"
... and accepts our mail.
Is there an easy way to have mail destined for this domain (wwd.von.ca) go
to the secondary MX instead of the first? Would the best way to do this be
to copy their domain data and claim to be authoritative for it on my mail
server?
Thank-you.
