Sorry, Neil is right, it is a bad practice.  We have many gateway machines
around here for our various local nets that have two ethernet interfaces with
the same name... this is NOT a problem, this is, in fact the "normal" way to
do it.

And it doesn't complicate things, all of our machines (except the one
definitive mail gateway) use the same (yes, EXACTLY the same) sendmail.cf
file and our host tables are Yellow Pages and therefore all the same, too.

It's HARDER to set the machine up with multiple names, then you have a bunch
of things to keep up with (let's see, which side of the machine do I want
this to work on!?)... of course, if your routing is set up right, even that
isn't too much of a problem, but it's still easier with one name.
