Hi,
I would like to redirect all DSN messages to the same bounce complex.
In the case where the recipient's endpoint is SMTP (author's endpoint is
LMTP)
and the recipient address does not accept the mail from this author (or
recip address doesn't exist),
the bounce message is redirected as configured in my main.cf using
smtpd_null_access_lookup_key and sender_dependent_relayhost_maps.
In the case where recipient and author are both LMTP endpoints and the
email is rejected by
the recipient, postfix automatically generates the bounce and then
delivers it via lmtp.
I cannot find any lmtp configuration or filtering option that will allow
me to forward
the bounce to the same bounce complex as specified in the
sender_dependent_relayhost_maps file.
