Hello,
I currently use relay_domains and relay_transport as a means to relay
email on to another mail server which hands off to the MDA. Everything
works well. Occasionally there may be a delivery problem when talking
to the relay_transport that results in a bounce being generated by
postfix - an expected behavior of any MTA. What I need to do is hide
details (the IP address) of the relay_transport in the bounce message
due to security concerns. I tried using the bounce template
configuration to do this, but postfix adds this information anyways. Is
there any way to hide this information?
Is this about the RECEIVED headers in the undeliverable message? If so
then you need a content filter or header_checks rule.
Is this about the remote hostname[address]:port in the server response?
If so then you need Postfix 2.12 with smtp_delivery_status_filter to
sanitise the delivery status message.

Thanks Wietse,
Its about the hostname[address]:port in the server response. I already
block based on bad recipients, but there are other types of bounce
messages sent that I need this to cover. I will try 2.12 out.
