Hi,
I have introduced helo_verify into my conf file to try to cut down on
the amount of spam we receive. While checking the logs I noticed a
couple of legitimate senders had been rejected at the helo stage. I
had thought of introducing a recipients_reject_except list to allow
those sender that we know are legitimate but for whatever reason are
not able to send "correct" helo commands. However looking at the
docs it looks like the reject would happen too early for the
recipients_reject_except to come into effect. Is that correct? Or would
a exception list allow those senders though? Is there some other way
I can do this - allow some hosts domain to by-pass the helo_reject. I
am finding the helo_reject a powerful anti-spam tool so I would like
to keep it.
