Topic: How can i set it not to accept return letters

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====

- Linux/BSD distribution name and version: centos7.6

====
Good day.
I deploy the iredmail for production.The mail set other user for sender, and send a message as a proxy, but the user received a return letter("Undelivered Mail Returned to Sender").
ex: a@test1.com use b@test2.com send email.The return letter cannot be send to B, but send to the special return mail ret@test1.com.
(1) How can I set it so that they can't receive the return letter?
(2) Can these returns be forwarded to a specific email address?
I tried many ways to solution it, but they didn't work.
Do you have similar cases or solutions.Thanks for your reply.

- is this what you're looking for? http://www.postfix.org/BACKSCATTER_README.html
- Do you have SPF/DKIM and DMARC DNS records for your mail domain name?

Re: How can i set it not to accept return letters

I've seen this document, but it should be used to block spam. I'm not bothered by spam.

I hope that the user will not receive the returned letters from the agent, and these returned letters will be returned to the designated mailbox.

For example, the program can set  'Return-Path:'  for Specify return address, does iredmail have a similar configuration?

Thanks.

Return-Path can be set by MUA.
Also, the forwarding server can enable SRS (Sender Rewrite Schema) to rewrite address.
