I have it completely disabled since the installation. (and I doubled checked the 
sysconfig/selinux file for this email. ;) )

I'm using FC-7 not 8... so I don't know what diff's might exist there... but..
moving along.

Hmmm, and in my case where it's disabled?

I would offer the argument that this is a matter of what user/group sendmail is 
running as vs. what user/group mailman was built to run with.

As for Postfix, I'm a sendmail fan and use it with all the other goodies
one might use with sendmail to control spam (mimedefang, spamassassin) so
moving from sendmail won't happen in the near future just as I'm comfy with
it and have my plate filled with other things (that are part of my j-o-b).

again, my SElinux is disabled, so what might you recommend?

Thanks for the fast reply!
