I supposed it might help if I posted the error from postfix. :)

Does this still seem similar to the procmail issue you were seeing
Paul?  I know that postfix tries to execute commands run via aliases
as the user which owns the alias file and I am guessing that's what's
causing the problem here.

Would changing /usr/lib/mailman/mail/mailman from lib_t to bin_t
negatively affect those using mailman with Sendmail as their MTA?

When I get a moment I'll boot to FC5 and try changing the context to
see what happens.

Thanks for the response.
