Were this me, I'd probably look at using something like:

    all mail going to $mailbox is considered a (un)subscription request;
    mail to $mailbox needs to be (gpg) signed;
    the subject: header contains the listname and a command;
    the body of $mail contains a list of email addresses, one per line

If the signature's valid, then to feed the body of the mail to
(add,remove)_members, stripping subject: as arg1 (listname) and arg2
as 'add' or 'remove', and turning the body into a tempfile to use.

As for invocation, it could be done directly as a pipe to a script, or
relying on cron to handle things; a second mailbox could be used, to
make things 'easier' for subscription/unsubscription.

I'm not doing this myself. There may be other ways. 

For Mailman 3,
and thereafter may be of interest.
