- Dan,
- Following up the last part of this, since it addresses a slightly
- different problem I'm having to deal with and the address reversal
- database is less-than-astonishingly documented....
- Two questions, assuming a reversal database that contains
- user1@my.domain user1@the.other.domain
- user2@my.domain user2@the.other.domain
- and use_reverse_database and reverse_envelope both set to 1 (the defaults)
-
- (1) When I use pmdf test/rewrite user1@my.domain, I get
- header From: address = user1@the.other.domain
- as expected, but
- envelope From: address = user1@my.domain
-
- Is this a problem in pmdf test/rewrite, or is the thing not going to
- remap both addresses?
-
- (2) Assuming that it does remap both addresses, or that it can be
- persuaded to do so, there is a prohibition in RFC1123 (section 5.2.2) on
- using anything but canonicalized names in MAIL FROM fields. I don't
- have any problem with this in my application, but I could imagine
- situations in which it would be necessary to apply a different rewrite
- to the headers and the envelope to conform to this rule. I infer that
- one might be able to do this by specifying reversal before PMDF address
- rewriting and then post-rewriting things using $B and $E, possibly in
- conjunction with $R. Is that the intent?
