I think I've got the bounce stuff fixed now, and I did turn on VERPing each individual message for a bit to see if that worked. It does, but it slows down delivery a bit since it can't batch send messages. Also, someone (Magnus?) suggested on irc that VERPing the individual messages could mess up some black/white/gray listing setups. I'm less concerned with that than I am about the possiblities for VERP to help us control bouncing accounts, but I wanted to discuss it here first. So, at the moment, I've set mailman to VERP password reminders and confirmations but not individual messages. List owners can turn that on if they want, though.
What Magnus was referring to is the ability with some list managers, just as djb's EZLM, to set up VERP where every single message has a different identifier. So messages from trilug might have an envelope sender of something like, "[EMAIL PROTECTED]" (made up syntax, but you get the idea). This causes problems with "graylist" spam detection (called auto-whitelist in SpamAssassin) that might keep track of things based on envelope sender. It isn't a problem if the envelope sender is the same thing for each message, which is how mailman does it. So we shouldn't need to worry if we enable VERP for normal postings in mailman.

Good description Jeremy, but let's deal with non made up examples. Here's an the Sender header from a message I sent while mailman's "Personalization" was turned on:
Sender: [EMAIL PROTECTED]
Here is the Sender header from your message (with mailman's "Personalization" turned off):
Sender: [EMAIL PROTECTED]
So, it looks like to me that yes, it is changing the sender header and it will affect things like Mangus is talking about. What am I missing here? Is it the fact that the sender will still be the same for all messages to a given subscriber even though it includes the e-mail address of the recepient in it? (i.e. mailman can use VERP to figure out who's bouncing, but not which message bounced?)
Cheers, Tanner
