Slightly related, Yahoo and Gmail classed as spam some messages which
had a different envelope-to than to, or envelope-from and from. The
headers_rewrite can't rewrite envelopes IIRC, but a global rewrite does.
Here are some details about headers_rewrite being ignored completely. I
tried numerous patterns, including very simple ones. Below is the one
which works fine as a global rewrite:
headers_rewrite = \N^([^+]+)\+([^+]+)\+onbehalf@???$\N $1@$2
It does take it into account (complains if it's invalid) but then fails
when I test with:
mail -s test SNIPPED+gmail.com+onbehalf@??? -- -froot@???
Debug shows no header is rewritten and the error message is:
SNIPPED+gmail.com+onbehalf@???
Unrouteable address
------ This is a copy of the message, including all the headers. ------
Return-path: <root@???>
