Topic: Problems receiving an email from other local postfix sending server
==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release): 1.5.1 MARIADB edition.
- Deployed with iRedMail Easy or the downloadable installer? yes
- Linux/BSD distribution name and version: CENTOS STREAM 8
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL
- Web server (Apache or Nginx): Nginx
- Manage mail accounts with iRedAdmin-Pro? No
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
Both platforms work fine. Iredmail works as designed and all users can sent and receive emails from around the world. A second local machine (Freebpx) can sent emails to the world, but not to an email domain hosted locally.
Find attached the log. Although I'm not an email expert, the sending log seems to tell me that everything was successfully sent. Iredmail logs seems to reject the same email, but not reason why exactly.
