The MTA at orig.com can now use the "Original-Envelope-ID:" to
determine whether the bounce is valid. Ideally, the ENVID would get
passed back on the DSN's RCPT command, but alas it does not. I
suppose if we are adding SUBMITTER to MAIL FROM, we could add ENVID
parameter to RCPT, like this:
EHLO third.com
MAIL FROM: <>
RCPT TO: <ann(_at_)orig(_dot_)com> ENVID=yf09+Cw
Why can't the DSN look like this:
EHLO third.com
MAIL FROM: <> ENVID=yf09+Cw
RCPT TO: <ann(_at_)orig(_dot_)com>
That would make for a very clean SES without munging the localpart.
In fact, I am not sure what ENVID is good for without it being
spit back in some manner.
