Well, it seems to be "partial" current practice. My public email address
goes to a forwarder (pobox.com) that, being fairly knowledgable in the
email area, will rewrite my address while preserving the detail portion
when forwarding it to my actual ISP. I know they understand the "+"
delimiter, but I haven't tested other delimiters.

Unfortunately, my current ISP rejects such addresses as Recipient Unknown!
This means that MY "local convention" is thwarted by my ISPs "border
servers".

I would love to point the ISP to an RFC that shows them what ought to be
allowed.
