[TriLUG] Another Stupid Sendmail Trick?

[Jon Carnes]

Well I'm not entirely sure what you want to do, but...
If you want to selectively route mail for "strutmasters.com" you can do
that with the mailertable in Sendmail:
  http://www.sendmail.org/m4/mailertables.html

You'll want an entry similar to:
  strutmasters.com 	smtp:[inhouse.server.com]

Good Luck!
