I think you just need the stuff from
http://www.greatcircle.com/majordomo/majordomo-faq.html#3.6
Sendmail allows you to rewrite incoming and outgoing addresses. The one
that handles incoming is virtualusertable.text. For a list called test with
the test-outgoing alias, I put the following into my virtualusertable.text
file and remade the db with the appropriate command:
test-outgoing@mydomain.com error:nouser User unknown
Sendmail can still get to the alias and expand it into the list of
recipients. However, any mail that appears at port 25 marked for
test-outgoing@mydomain.com will bounce back with "User unknown".
[..]
Basically you make it so that that -list address only works from within
your host.
This can (and perhaps should) be used in conjunction with renaming it as
Dan suggests (which is kinda security through obscurity).
