I was just struggling for an hour with the meaning of > It might help to quote what you want to match. when the following arrived, thank goodness: < SpamAssassin joins all mail header fields with the same header name < into one multine string of header field bodies,
Ah, no wonder $ matched but ^ didn't. Delivered-To: "[EMAIL PROTECTED] mailing list users@spamassassin.apache.org" < so whenever one uses a ^ or $ in a pattern, one is almost obliged to < append a /m flag, otherwise one risks being at a mercy of malicious < senders... Depending on a situation, this can be a security risk. Sure wish Mail::SpamAssassin::Conf would mention all this where it discusses headers. Also it should mention loss of \Q\E.
