Question How can I configure all bounce messages to go to the sender of the message?

[Manuel Garcia]

Server operating system version

Ubuntu 24.04 LTS

Plesk version and microupdate number

Plesk Obsidian 18.0.70, actualización 3

I'm trying to configure bounce messages to be sent to the senders.
I have the following lines configured:
notify_classes = bounce, 2bounce, data, delay, policy, protocol, resource, software
bounce_notice_recipient = postmaster
delay_warning_time = 35s
minimal_backoff_time = 30s
maximal_backoff_time = 4000s
maximal_queue_lifetime = 7d
bounce_template_file = /etc/postfix/bounce.cf

However, I get the messages to reach the postmaster but not the sender.
I have this configuration in /etc/postfix/main.cf
Is this the correct location?
Do I have something configured incorrectly?
Thanks for the help.

Hello, @Manuel Garcia . If I am not mistaken, Postfix does bounce to senders by default without needing any specific configuration. I would say the issue here lays with the delivery of the message to the sender rather than the configuration itself.

It is correct that, as stated by @Sebahat.hadzhi, Postfix is bouncing messages by default to the original sender - that is, Postfix will at least try.

The config line

bounce_notice_recipient = postmaster

will allow bounce messages to be sent to the postmaster, in addition to the bounce messages sent to the original sender.

Stated differently, if the original sender is not receiving bounce messages, but the postmaster is, then the following applies : there is an issue on the mail server side of the original sender, but bounce config is proper (given the fact that the postmaster receives bounce messages).

I hope the above helps.

Kind regards....
