As you can see from the nslookup of ATT.NET that follows, they have lots of
MX records, all the same IP address. On nights like tonight when AT&T is
jammed, this can block a delivery thread for over an hour.
Is there a reason why getMailServers [actually, DNSServer.findMXRecords()]
should not return a collection containing only one entry per IP address?
