2) I want to forward bounces to a specific host. I was looking for a
way to specify a relayhost or a transport for that class of messages
and couldn't find a way to achieve that.
There is no RFC that requires this. I am highly-suspicious when
people want to handle NDRs differently; they usually have a problem
that they want to cover up.
The RFC reference was for 1).
This is more about policy than anything else.
This is the scenario.
Box 1 : just receive email from "outside" - inbound flow.
Box 2 : used to sent email to the "outside" - oubound flow.
Firewalls are set in a way that don't allow Box 1 to send traffic to
the "outside", so i need to route bounces (and defers) generated in
Box 1 to Box 2
fix *why* you create bounces at all on a inbound MX
http://www.postfix.org/ADDRESS_VERIFICATION_README.html#recipient in
case of not able to list some domains you accept mail for in
"local_recipient_maps" is the way to go
we list all domains where we have the RCPT's in
"/etc/postfix/skip_rcpt_vrfy.cf" and anything else needs to pass
"reject_unverified_recipient" and so that way we can even offer
spamfiltering services for customers with their own Exchange server
without create a single bounce
smtpd_relay_restrictions =
reject_unauth_destination
check_recipient_access hash:/etc/postfix/skip_rcpt_vrfy.cf
reject_unverified_recipient
