[Mailman-Developers] Subscription Audits?

[Mickey Chandler]

I've done a couple of searches and noticed that there has been some talk of 
improving user stats.  The wishlist mentions "Keep user-centric stats, such 
as the date the user was subscribed, the date of their last change to their 
account, the date they last sent a message through the list. Perhaps also 
log each message they send through the list."

Would it be possible to extend this to a full blown subscription audit 
trail which would also keep track of how the subscriber subscribed and 
unsubscribed, what method they used to confirm (email or web), and what IPs 
those requests came from?

With the new anti-spam laws coming into play in California and the EU I'm 
starting to wonder if the lack of this information will have to force me 
away from Mailman for an announcements list that my company runs so that I 
can comply with the various laws.
