Hi everyone, I am using a test mode server with Google Cloud Services platform, the issue is Google cloud does not release port 25 for mail service therefore i cannot use and start postfix, dovecot and Opendkim. All services are stopped.
Upon checking online for a few solutions, I found that we can replace the Port 25 to another one for example 547.
My question is, can we do that without breaking the aaPanel code? Anyone has tested this out?
