Hey all,
The dayjob is attempting to tie VERP into our ticket system (RT with
postfix), and it would be useful to encode not just the magic "from"
address, but ideally the ticket number as well, so that a bounced
reply to the customer can be added to the ticket stream.
RT includes the ticket number in Message-IDs. Could you parse that out
of the bounce instead of creating a custom VERP? I believe the point of
attack would be the RT 'bouncehandler' mechanism which already does
magic subject detection.
So if normal verp (per the docs) rewrites owner-listname@origin for
user@domain, by setting a sender such as
owner-listname+user=dom...@origin...are there any "gotchas" to instead
calling verp with a value such as ticketbounces-ticketnumber@origin,
and letting VERP rewrite it to something like:
ticketbounces-12345+bob=customer.org@origin
So thus we know which conversation the bounce was on.
VERP doesn't have a formal RFC I can read, and I don't see a reason it
shouldn't work so long as we set up the right handler, but if anyone
has any other insight, I'd love to see it.
(Ignoring the fact that sometimes stupid filters like office365 just
silently discard or accept and route to spam instead of properly
bouncing -- we can't really solve that).
