Do you have SELinux in enforcing mode?

Hmmm, on an F8 box with a fresh install of mailman and everything else
up to date (including the updates-testing repository), I don't see
this particular error. I do get a failed delivery with SELinux in
enforcing mode though. The bounce in my case is:
----- The following addresses had permanent fatal errors -----
"|/usr/lib/mailman/mail/mailman post test-list"
(reason: 1)
(expanded from: <test-list@xxxxxxxxxxxxxxxxxxxxx>)
----- Transcript of session follows -----
post script, list not found: test-list
554 5.3.0 unknown mailer error 1
Setting SELinux to permissive lets the mail go through. So there
appear to be some policy tweaks needed.

It's likely that testing with SELinux in enforcing mode hasn't been
tested well. Since mailman can be used with a variety of MTA's and
involves a bit of work after installing the rpm to finish the setup, I
can undertstand this. I hadn't tested mailman with sendmail in many
years until today. I typically use Postfix since it integrates with
mailman much nicer IMO.

See if running "setenforce 0" as root changes the behavior. If it
does, then we should gather up the AVC messages from SELinux and
report them to bugzilla so Dan Walsh can push out a corrected SELinux
policy that allows mailman to operate with sendmail.
