For one thing, mailman.bates.edu is a CNAME alias that points to
postoffice03.bates.edu, so all MTAs should be re-writing
mailman.bates.edu anyway -- but not to simply bates.edu.
If you don't want this kind of rewriting to be done, then you can't use
CNAME aliases in the DNS. Give mailman.bates.edu an IP address (like
188.8.131.52), and then set up reverse DNS for this IP address so
that mailman.bates.edu is one of the answers given. It should be okay
if postoffice03.bates.edu also points directly to the same IP address
and the reverse DNS for that IP address also includes that name in the
response, but you need a full forward->reverse->forward matching for any
given name you're going to use.
Also, I would suggest using a service name that does not include the
name of the software in question. So, lists.bates.edu instead of
mailman.bates.edu -- this gives you the option to change the software
used in the future, instead of having a case where you have Mailman
serving mailing lists on a machine known as listproc.bates.edu, or
whatever. This is generally a good idea for pretty much all services,
so bugs.bates.edu instead of bugzilla.bates.edu, webmail.bates.edu
instead of squirrelmail.bates.edu, mail.bates.edu instead of
delivermail.bates.edu, www.bates.edu instead of tomcat.bates.edu, etc....

Keep in mind that some configuration options will only be effective at
list creation time. Once the list gets created, even if you go in and
change those options, you will only affect new lists that get created
and all existing lists will be unchanged.
So, make sure you're changing the right option, and that the option in
question for a list is something that can be changed after the list has
