A few mailing lists that I've seen have started implementing an automatic
user unsubscribe. Basically, if you want to keep the service, you have
to send in a new subscription notice every n days (usually once per
The idea is that this keeps down on garbage in your list. For large
lists (>10000 users) garbage is a big problem.
The changes needed in Majordomo to support this are not very drastic.
Simply adding a "tab" and a UNIX time integer representing the subscribe
date to the user list file would add all the information you need (note:
this is something that would be nicely implemented with .db user lists,
hint hint :-)
Once per day, a program could run and see if the person will expire in
the next week. If so, it would send a message notifying the user that
she should resubscribe if she is interested in continuing. When the user
expires, she is automatically unsubscribed.
Does this sound like something anyone would be interested in implementing?
