Hi,
With this:
Received: from public30108.xdsl.centertel.pl (HELO
marcin-8963fd6f) (79.163.117.156)
my postfix setup would have simply dropped it on the floor at the
HELO/EHLO. If it doens't HELO with an FQDN and a proper rDNS, we don't
talk to it.
Kurt, can you explain how you're doing it with postfix?
I'm not kurt, but how about
reject_unknown_sender_domain
That's what I use.
That will reject unknown sender domains. How about:
reject_non_fqdn_helo_hostname
An example from the logs:
Oct 16 00:00:05 smtpgate postfix/smtpd[80448]: NOQUEUE: reject: RCPT
