^...@*\.umn\.edu
works, but it doesn't do what you mean. It matches any address that
contains ".umn.edu" anywhere within it including such things as
user.umn....@example.com and u...@mail.umn.education.net. It literally
says zero or more anything followed by zero or more '@' followed by
'.umn.edu' followed by anything.
What you want for this is
^...@.]umn\.edu$
which matches any address that ends with "@umn.edu" or ".umn.edu"
The attempt at negative expressions for suzane and jerry is completely
invalid. The spaces around '|' are significant. They will be part of
the regexps and need to match, and '=!' is not valid.
First, are suzane and jerry list members? Anything you put in
*_these_nonmembers only applies to nonmembers. These will not serve to
hold posts from members that would ordinarily be accepted.
If suzane and jerry are not members, just put
^...@.]umn\.edu$
in hold_these_nonmembers and put the two lines
suz...@stat.umn.edu
je...@stat.umn.edu
in accept_these_nonmembers which is tested first. lines that don't
begin with ^ are simple addresses, not regexps.

This one matches the literal addresses 'li...@stat.umn.edu' and
'li...@stat.umn.edu' plus any address that does not end with
'@anything.umn.edu' or '@umn.edu'. If that's what you want, it should
work, but remember it only applies to non-member addresses.

Mailman doesn't 'build' those lists except that when you process a post
from a non-member in the admindb interface, you can check a box to add
the From: address of that post to one of those lists.

A 450 from Postfix during SMTP should result in that one message being
retried once every hour for 5 days, but the same will happen with the
next message and the next.
If these 450 statuses are undeliverable local addresses, put
unknown_local_recipient_reject_code = 550
in Postfix's main.cf to return 550 instead which will result in an
immediate bounce.
