Probably because they match expressions in your undisclosed [!!] file of header_checks(5). > Hence my *questions*: is there any black magic implemented in cleanup > header checks?

The black magic is either regexp_table(5) or pcre_table(5), as determined by your undisclosed [!!] "postconf -n". postmap(1) is the ideal tool for debugging all kinds of Postfix lookups. See "-q".

The real problem is that you're trying to use the wrong tool. :) header_checks(5) is rarely the right approach, but it's often a first choice for people who: 1. don't understand regular expressions 2. don't understand email Now, what was the undisclosed [!!] reason you thought you wanted to reject these headers? See the [!!] for items you might need to provide. -- Offlist mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header
