[Mailman-Users] Interesting Mailman-Postfix Churning: User unknown in localrecipient table

Jeremy Butler Thu, 20 Mar 2003 18:19:33 -0800

I encountered an interesting case of, I think, Mailman-provoked Postfix churning this afternoon. For several hours, Postfix and Mailman kept going in circles (see below). Fortunately, when I restarted Postfix, the churning stopped.

But, obviously, I'd like to avoid a repeat of this. And so I'm looking for advice.

I believe this churn was initiated when a Mailman list ([EMAIL PROTECTED]) tried to tell a subscriber ([EMAIL PROTECTED]) that he had been unsubscribed. Mailman sent a good-bye note to [EMAIL PROTECTED], which appeared to be on the same system as it was, BUT [EMAIL PROTECTED] was NOT actually a valid account on that machine. In fact, I deleted it because it wasn't a valid account.

Can anyone 'splain to me why the lack of a valid recipient led to such churning?

Thanks!
