At a guess, enclosing hostnames in []'s would eliminate that- if you're
relaying mail for something, for instance, you may want to explicitly
specify a destination hostname rather than allowing sendmail to try an
MX lookup on that name.

You may also be able to do something like:

define(`SMART_HOST',`esmtp:[host1.dom:host2.dom]')

I have no idea whether either of these would work though.  <g>
