Background is that my header checks should match headers (ex marked already as spam by sending server) of messages which I do not want to feed to my proxy filter. As processing msg via my proxy filter invokes 3 av-scanners, spamassassin and several other plugins of that filter software. Much work for a message that after proxy filter will be rejected by postfix header checks anyway :-) So if I got you right: it's not possible to run header checks before proxy filter.
