Well, sort of.  I suspect they are all because we don't yet have working
reverse DNS for the crosswire.org server at its new location.

I'm out of time to fix reverse DNS the way I really want to fix it.

So, for now, Troy, please contact the colo provider, and have them
provide reverse DNS for our set of IPs, 64.71.190.106 to 64.71.190.110,
and have the PTR records for all of them return crosswire.org.

We can revisit this later, but for now we need *something* for reverse
DNS to keep other email servers, including Hotmail, happy.

I just checked, and crosswire.org is the primary hostname in the exim
(mail server) configuration, so that's the best name for reverse DNS
lookups to return, just in case some really picky mailservers out there
cross-check that the forward and reverse DNS match up with the name in
the SMTP banner :)

Thanks,

Jonathan
