He could have been unsubscribed automagically due to too many bounced messages to his address.

Is this a cPanel installation? I had a mail (not list) user whose address was suspended (no incoming mail, no login) and afterwards deleted. After some time, the address was re-created and it showed up with the last status of that address (suspended) just after re-creation. This behaviour might also apply to lists, but it is just an assumption - not knowledge.

If he was taken off the list due to bounces - why should Mailman send a message to an address which does not accept mails?
