Hi, I want to scrub certain kinds of headers for all incoming messages so that I can use them for myself—and trust them. In particular, I want to get rid of all headers which start with ‘Spam-’, no matter what comes after that prefix (be it ‘Spam-Score’, ‘Spam-Whitelisted’ or whatever my yet-to-be-designed antispam filters will come up with).
The Exim Specification mentions in §43.25 that ‘wildcards are not permitted, nor is list expansion performed […] however, both connection and message variable expansions are performed.‘ I have tried to find some kind of string expansion which would give me a list of all message headers which start with my chosen prefix, or some other kind of trick to get similar results, but so far, I didn’t find anything. Of course I could list all possible combinations of ‘Spam-…’ that I can think of, but this is kind of a losing battle… Any ideas are appreciated. Cheers, Stefan -- ▪ Die Internetbleibe.
