Hi I have a line like this in my logs: mail #554 5.7.1 <SPEXCH07.sp.com>: Helo command rejected: Host not found ##
This is clearly because I have reject_invalid_helo_name in my main.cf Unfortunately, the fools at steelpartners.com have decided it's quite okay to helo with sp.com (which actually resolves to Scottish Power). I'm reluctant to remove this as it stops about 25% of my spam attempts. I thought about adding it to /etc/postfix/helo_checks but that is checked AFTER permit my networks, so it wouldn't do any good - right? If I added in a check_helo_access before reject_invalid_helo_name that would work, yes? Or would it be better to turn that line into warn_if_reject? What do other's feel about that line? Simon
