I am currently configured so if any list subscriber's address is bad/undeliverable, those bounced messages go into the Bad Mail folder. I age off Bad Mails on a periodic basis to keep down the size. Some of my larger lists now have many bad addresses as the recipients have moved on. Thus any post to that list causes a significant number of refusals and Bad Mails.
Does anybody have a method of automatically unsubscribing those subscribers which always bounce? It would be neat if one could set a limit - e.g. 3 consecutive bounced messages will cause the subscriber to become unsubscribed with an notification e-mail being sent to the lost owner. Or some such.
