Hi. __TO_EQ_FROM_1 and _2 in 72_matching.cf triggers on emails where To: isn't the same as From: in certain conditions.
If the first of these headers only has an addr-spec and not [display-address] angle-addr (according to RFC 2822), the regexp matches the last character of the addr-spec. If that character exists in the last of the two headers, the rule will match. Example headers of a matching email (munged to protect the innocent): Subject: Vacancy application: Someone is looking for a Centre Manager To: exam...@chalmers.se From: Simple Example <c...@example.se> MIME-Version: 1.0 A non-matching example: Subject: Vacancy application: Someone is looking for a Centre Manager To: Bad example <exam...@chalmers.se> From: Simple Example <c...@example.se> MIME-Version: 1.0 I'm smart enough to detect why this happens, but not how to design a better regexp. :-) //Christer -- | Hagåkersgatan 18C | Phone: Home +46 31 43 52 03 CTH: +46 31 772 5431 | | S-431 41 Mölndal | Cell: +46 707 53 57 57 | | Sweden | Mail: m...@chalmers.se | "An NT server can be run by an idiot, and usually is." -- Tom Holub, a.h.b-o-i
