Now that resolver is used, mail ignores 'mailhost' in /etc/hosts

[Mark Eggers]

Another way to do this is to set up the domain name system with a
mailhost.domain as a CNAME to the real host.  This seems to work
with Sun 4.0x, and 4.1 running the supplied sendmail stuff (one slight
hack to get it to recognize the fully qualified domain name as local), with
a real sendmail (read sendmail 5.64 - IDA 1.3.4) as the mail host.
