Postfix Sends Duplicate Forwarded Email When Recipient and Forward Email Addresses On Same Server

CyberPanel Project Bug Report
#1

See above. To reproduce this bug, create test1@mydomain.com and test2@mydomain.com on your CyberPanel server. Set test1@mydomain.com to forward to test2@mydomain.com. If you send an email to the test1, test2 receives not one but two copies of that email. I found the fix! Add the following line to /etc/postfix/main.cf:

enable_original_recipient = no

After, you should no longer receive the duplicate emails.

#2

This didn’t work for me.
I am forwarding to another external domain and it’s going 2 times.
