Yes, I created a "lists.forensicpath.us" early on.

Done.   I started getting the disappearing mail problem again, though
none of the  references to errors from the changes I made originally. 
After spending a few hours going over debug files, I noticed that I
kept getting a pam error.  The mails were getting rejected over
authentication errors.

It turns out it was all a permissions problem with /sbin/unix_chkpwd. 
Apparently the sticky bit was not set correctly on installation.

Here's a discussion of the problem:

https://unix.stackexchange.com/questions/422411/pam-authentication-failure-with-valid-password

I still don't understand why this was a problem with mailman and not
with "regular" mail, but doing the "chmod u+s /sbin/unix_chkpwd"
resulted in things magically working just like it's supposed to.

Thanks for the help!
