I remember now when I implemented SRS, I configured separate postfix
instance for outgoing mail. This is the postfix issue described in
postsrs docs: canonical maps are processed when mail is being received.
Yep, I have 2 separate deployments, one for incoming mail which includes
antispam check and verification of domain, and second for outgoing mail
with postsrsd and aliases database.
This outgoing instance rewrites mail sender, the default postfix
instance only rewrites recipient.
This way, only outgoing/forwarded mail is subject to sender rewriting.
So you say it's better to do recipient_canonical_maps on incoming mail?
How it will improve situation? SRS will still throw same error and
Postfix still reply with 4xx, no?
