I would like some feedback concerning a use case
Description
I have a question about the configuration of my mail server. It seems that I am unable to receive e-mail for a legitimate internal user.
This user, let's call him [email protected] can connect via IMAP and send e-mail to [email protected].
[email protected] receives the e-mail and tries to reply, except it never gets received by [email protected].
Troubleshooting:
The port is open, and the correct service is listening on the port, confirmed using: https://canyouseeme.org.
When I use https://smtpserver.com/smtptest to test the actual mail response when [email protected] sends to a legitimate user [email protected], I get the following response:
554 5.7.1 : Client host rejected: Access denied
Config:
PERMIT_DOCKER=none
hostname: mail.domain.tld
Logs:

Logically there should be list of domains to "accept", or least accept the existing users by default. However, after countless searches and reading through all of the documentation, it is still not clear what I am doing wrong.
Any help is greatly appreciated.
