That's the point though - you can't know all the systems you may be breaking by changing the way your MAIL FROM works.And BATV will never be widely deployed because it breaks every single system out there that keys off the return path. And there are a lot of these systems.I keep hearing that, but other than a few ezmlm lists and the occasional tired fax gateway, I never run into them. Where are they? Here's a few that I've told you about before: Whitelist/Blacklist entries Quarantine systems Anything based on .qmail files Some auto-forwarders Auto-responders Now you can potentially whitelist around these issues (to some extent), but while that works for geek mail systems it doesn't scale up very well. I know you (personally) whitelist around some problem systems in your implementation but can you expect Grandma to do that?
