Hi,
Sorry for posting on a bsd list but i figure there's more than a few
sendmail experts here.
I would like to run reverse dns checks on one of my boxes but the
check_rnds macro looks a bit overkill to me.
I want to reject the mail if there's no reverse dns, but not if there is
rdns but the PTR loop isn't closed (which is very common).
So accepting these types:
reject=451 4.1.8 Possibly forged hostname for
but rejecting these types
reject=550 5.7.1 <........>... Fix reverse DNS for
.......................
In sendmail, FEATURE(`require_rdns')dnl seems to do both.
many thanks
Paul.
