The easiest way I see to accomplish what you want is to avoid Majordomo 
entirely (although it would be a lot easier if you just moved the whole 
works to a Mj list and not worried about the issue), and just install 
demime as a front-end filter *before* the other list-management 
program.  (Demime is an excellent program written by Nick Simicich, and 
is available at http://scifi.squawk.com/demime.html and some 
open-source repositories.)

Using the mail alias feature of the mail server on the site that hosts 
the list (e.g., /etc/aliases or /etc/mail/aliases for sendmail & UNIX), 
make the list posting address a pipe (or equivalent mechanism) to 
demime, which then delivers the message to the list-management program.

For a Majordomo list it's something like:

mylist: "|/usr/local/majordomo/demime '|/usr/local/majordomo/wrapper 
resend -p bulk -M 10000 -l mylist -f mylist-owner -h myhost.com -s 
mylist-outgoing'"

For a non-Majordomo list, it might be something like:

mylist: "|/usr/local/bin/demime mylist-post"

where "mylist-post" maps to the input of your list-management program 
for the list "mylist".
