Hello :-)
I am running postfix-2.1.5-3.4 on SuSE Linux 9.2.
Now I want to block all mails from "MX" with just an IP adress as DNS,
like 124.199.17.57, where
nslookup 124.199.17.57
** server can't find 57.17.199.124.in-addr.arpa: NXDOMAIN
In Postfix > 2.3 reject_unknown_reverse_client_hostname would be fine -
as far as I understand. If I can't update immedeatly to 2.3 - is this
possible for my postfix version, too ?
Rgeards,
