Sounded easy (and probably is), but, don't see it. I know I can add header_checks and have a rule in it to ignore a header, which is what I want to do. Specifically, the header that is added by reinjection after an after queue content filter that shows received from localhost.
header_checks is used in the port 25 smtpd server. Normally, one has a no_header_checks on the reinjection smtpd server as you don't want to re-check the same rules, as I do not. Some of them might even cause trouble. So, I don't (can't) want to use the same header checks. I want to use a new header_checks file which just has one rule to ignore that header, but only on the reinjection smtpd server. However, this is not an option on smtpd. receive_override_options doc says you can disable things, but, shows no syntax for enabling things, though confusingly it says "Enable or disable", implying it may be able to enable, and perhaps even set header checks? Any good solution? Steve
