Huh? Where does it say that people with more than one mailbox aren't
allowed to use A-R ? The point I'm making here isn't about different
policies, it's that you can only believe an A-R header if the path it took
to get to you is good. We don't all get our mail via a VPN direct to
Cisco global HQ, you know, and the more unlike that a mail system is, the
more likely it is that A-R will be useful.

Perhaps, but in that case A-R is totally useless, so why waste your time
I have described an actual not-contrived use case for multiple A-R
headers, based on filtering that I'm doing right now. I wish you and Mike
would stop saying that I'm lying.
