[OT] username+whatever addressing

username+whatever@myisp.com addressing is very handy. If your ISP
implements it, all such mail goes into username's mailbox with
the "+whatever" still included. Among other things this makes filtering
easy.

AFAIK, this has not made it into any RFCs yet, but there is a document
around that describes it. I have not been able to find it by searching.

Anyone have a pointer?

TIA,
