To provide a concrete example,
Return-Path: <bounces+245234135(_at_)bounces(_dot_)hospital(_dot_)com>
From: Mommy Dearest <new(_dot_)mother(_at_)example(_dot_)com>
To: All and Sundry <all(_at_)example(_dot_)com>,
<sundry(_at_)example(_dot_)com>
Sender: greeting-cards(_at_)bounces(_dot_)hospital(_dot_)com
Reply-To: Mommy Dearest <new(_dot_)mother(_at_)example(_dot_)com>
or, perhaps,
Return-Path: <bounces+245234135(_at_)bounces(_dot_)hospital(_dot_)com>
From: Mommy Dearest <greeting-cards(_at_)hospital(_dot_)com>
To: All and Sundry <all(_at_)example(_dot_)com>,
<sundry(_at_)example(_dot_)com>
Sender: greeting-cards(_at_)hospital(_dot_)com
Reply-To: Mommy Dearest <new(_dot_)mother(_at_)example(_dot_)com>
I want to quote an actual message a greeting-cards provider sent me:
The "from" name and email address are set to those of the member.
We're whitelisted at AOL and Yahoo, and the whole thing works very
nicely on the whole!
At present, bounce messages are of course sent to the original
sender (our member). It would in fact be quite nice if these could
be sent to us instead, so that we could intercept them and send the
member a slightly more friendly non-delivery notice than is the
norm.
So these folks actually to be SPF compliant; they want to change the
return path and handle the bounces themselves. It's just a matter of
making all the other pieces come together.
