Check out ftp://koobera.math.uic.edu/www/proto/verp.txt . VERP stands for
Variable Envelope Return Paths, and it's basically just having the recipient
address encoded in the return address. Bounce messages are thus targetted at
that specially-created address which lets your bounce handler determine
whose address bounced without parsing the actual bounce message.
If you're a subscriber of <firstname.lastname@example.org> and I sent a message to that list,
you would get a message with an envelope sender of
<email@example.com>, I would get it as
<firstname.lastname@example.org>, etc. (with the 17 refering to
this being message 17, so my bounce handler (test-return) can figure out
which message bounced).
