Meeting rules in re Subsscribe / Unsubscribe can be a challenge, as the RFC's are not even the tip of the iceberg. There is government legislation and admin law all over the lot - more often than not written by the compuer illiterate. Exim - and/or a decent MLM working with it - can do what you ask. Finding out *what to ask* across multiple jurisdictions is harder. Mailing List Manager user mailing lists are perhaps a better place to look.
