Ahh.. my only use so far has been where a machine has a DNS entry that
matches its unix name (say, but also needs to be
known by other names - www and lists.

The only problem that has been so far, and is proving to be again, is
that lists under majordomo 1.94 get sent as the real host, and when
using a linux box and pine to send mail to a cname'd host, the
delivery is instead attempted to the real machine name.  I suppose an
IN A and/or IN MX record might fix that.  Should dig out my bind book
and try to work this out.
