I agree with your analysis.

*Your* procmail only sees headers and body. Consider in .procmailrc

EnvelopeTo = $1

* EnvelopeTo ?? ^mailman$
|sudo -u mailman /var/mailman/mail/mailman post mailman
* EnvelopeTo ?? ^mailman-admin$
|sudo -u mailman /var/mailman/mail/mailman admin mailman
and similarly for the other lists.

Then in sendmail.mc, you invove procmail with a -a argument equal to
the envelope recipient (-a $h I think but don't hold me to it).

Don't need to do that. Just pass the envelope recipient to procmail as

You can set full personalization for the list (if
OWNERS_CAN_ENABLE_PERSONALIZATION = Yes in mm_cfg.py) which will send
a separate message to each recipient with that recipient address in
To:, but you don't need to do that (am I repeating myself).
