Hey,
Looks like postfix was not compiled with tcpwrappers so I’m trying to figure out how to restrict incoming email from two domains on a couple of boxes.
Basically our domain, and google. Any suggestions, or should I be poking about on the postfix user forums.
SLES 11sp4 and SLEs 12sp1
Thanks,

That expertise would appear to NOT be here, or maybe the holiday month has
kept folks with that expertise at bay.
It may be worth posting in the openSUSE forums, not because they have
anything to do with SLES, but because folks who work with Postfix on that
side may know if you can compile and add a library to the system to enable
the functionality without rebuilding all of Postfix, or they may just know
of alternate ways to do what you are after, maybe with anti-spam software
that can sit between Postfix and the inter-tubes.

Good luck.

From a quick search I think you can achieve this by adding domains to
/etc/postfix/access although this seems to require an entry for each
domain you want to block (rather than block all then allow specific).
However it looks like if you change smtpd_sender_restrictions in
/etc/postfix/main.cfg to pcre:/etc/postfix/access (from
hash:/etc/postfix/access) you my then be able to reject based on regular
expressions, in particular “!/pattern/flags result”.
