Indeed, a strange problem.

Have you upgraded recently and this is your first list created since the
update?  We've seen this scenario several times in folks who have
upgraded in the past and are just now adding new lists.

There are several things to check...
 - check to be sure your settings are correct and up-to-date in
mm_cfg.py, if you upgraded you'll need to add certain new settings that
are set by default in the older lists, but maybe set incorrectly in the
new list until the configuration is brought up-to-date.
 - check your relay rules for your MTA and make sure it accepts all mail
for relay that is sent to 127.0.0.1, especially mail from
ultrascan.uthscsa.edu
