The helo host seems to change ever time; at least there are a lot of
them.
I just want to check here: is it safe to change my check_helo_access
from a hash to a regexp, and do:
/msp.secure-24.net/ OK
Is that likely to cause me any problems?
Hmm, I just tried it, and it didn't actually work! Anyway, any advice
on
this would be much appreciated...
You've got reject_unknown_helo_hostname in a smtpd_*_restrictions list.
Which one is unknown, as you've ignored the suggestions provided when
you subscribed here and about a dozen times per week on the list about
how to help us help you. The ordering of directives in each restriction
list and which list has reject_unknown_helo_hostname in it determines
how you would need to whitelist patterns against it. Provide postconf
-nf output for more specific help.
Be aware that if you use reject_unknown_helo_hostname you will have a
steady stream of cases for which you will have to make special
exceptions. How steady that stream is depends more on your volume and
diversity of legitimate mail than on how heavily spammed you are.
