MailMan has a "preapproved" list, but you need to add names to it

Give the list-admin password to multiple people.

Definitely. And it can even notify you when it does so.  Oh: it can
either delete them, or simply disable them.

Definitely. Same for unsubscribe.

Yes and yes.

You'll probably be more constrained by your network than your MTA.

I don't have any hard data on Mailman/sendmail using bulk vs.

I don't think it handles this.

Definitely. You can make the subscriber list: open, open to subscribers,
admin only.

Python is much more approachable than Majorpaino's perl, but you would
still need to do some coding to get this feature.
