If all options fail, you can fall back to your MTA logs.

Ah! Excellent call!
- grep for the subject of that recent post from the mainlog or whatever you call it. In Exim we generally call it mainlog (or main.log). If you were logging subjects, then you can tie the subject to the recipients of the mail. Everyone logs the recipient details, right?
I think subjects are generally not logged by default, but message-ids usually are.
I am very sure this will give you the list of subscribers.
I'm not so sure. If you're VERPing or personalizing it will. But if you're not, then I think many MTAs log only the first of the list of recipients at one MX.
Still it should be a very useful resource for recovering a mass deletion.

I was imagining a situation like mine. I log message subjects and a lot of other things with my Exim MTA. When Exim gets a post to be distributed list members it also logs all the recipients as it sends out. Not sure about Postfix though.
