Hi,
We've been using RBL's very successfully but recently had quite a
few false positives, mainly from Open Relays. Obviously we can
choose to warn or reject, thats fine.
A user suggested the following:
Why can't you check when sending outbound mail and report to the
sender that the person recipient may not be able to reply as the
they are in an rbl.
There are obviously issues with this, but this may give some
warning to our users who are trying to communicate with those
inside open relay systems.
I haven't examined the code but my guess is that it needs a
call to the RBL at some point after the MX lookup.
Any thoughts ?
Philip is this possible ?
