The MUUG mailing list program, Mailman, is mostly responsible for those
headers and whether reply-to goes to sender or list.  It's a
configurable option for us admins.  However, just like you saw, I find
that sometimes Mailman does weird things and sometimes just hitting
reply will go to list and sometimes just to sender.  I haven't seen
much rhyme or reason for that yet.

Most MUAs (like what I use, clawsmail) has a separate reply-all and
reply-sender buttons and I try to use those exclusively for muug list
replies so I know precisely who it's going to without having to
double-check the headers.

Maybe others more familiar with this header/mailman behavior can offer
some guesses as to why mailman sometimes gets it right, and sometimes
wrong.
