Rae, the following works for me, and requires procmail.
A remote server sends an email message from a web form, and my Mailman
server handles the request. I have to substitute a real listname for 'list'
below because I have about 15 lists that do this.

/etc/postfix/aliases:
list-special: "|/usr/local/bin/procmail -m /etc/procmail/.list.procmailrc"



/etc/procmail/.list.procmailrc:
TMPDIR=/tmp
MAILDIR=/dev/null
DEFAULT=/dev/null
LOGFILE=/dev/null

# Remote script writes a From of someone at somewhere.com

* ^approve PassWord subscribe
| grep ' subscribe' | sed -e s/.*=//g >> /tmp/list-subs; \
   chmod 666 /tmp/list-subs

:0Bwc:/tmp/listunsubs.lock
* ^approve Password unsubscribe
| grep ' unsubscribe' | sed -e s/.*=//g >> /tmp/list-unsubs; \
   chmod 666 /tmp/list-unsubs
}

if [ -s /tmp/list-unsubs ]; then
/usr/local/mailman/bin/remove_members -f /tmp/list-unsubs list
