Ok, I see the problem.  In that case you want the next level up of
hack.  You want to define a mailertable as such:

        FEATURE(mailertable)dnl

Then create a mailertable file.  Put it in /etc/mail and crunch with:

	/usr/sbin/makemap hash mailertable.db < mailertable

As an example of the things you can do, here are the last few lines of
my mailertable file:

    # spamsters, they have a problem setting up their MX's correctly.
    # we will fix things up for them.  wouldn't want them to miss their bounces.
    t3-com.com		esmtp:nancynet.com

    # more spammers with intentional MX problems.  Never say we
    # aren't nice to these folks.
    .algonet.se		esmtp:algonet.se

    # llnl can't get their mx's setup correctly.
    .llnl.gov		esmtp:llnl.gov

    #
    .bitnet			esmtp:talcott.harvard.edu
    #
    .uucp			esmtp:uunet.uu.net
