Hi Mailcowers : )
I am having trouble sending emails in my application, I have the error below in the queue queue for all the destinations I tested (outlook and gmail).
As it is a timeout, the first thing that comes to mind are Firewall rules. I configured a rule to allow all outbound protocols in my provider that hosts Mailcow (Google GCP Platfform) and tested the ping to several addresses like outloook and gmail, being successful. Still, I’m having the same timeout problems.
What could it be? Is there anything necessary to do within mailcow.conf to list my VPS network settings within Google Cloud Platform?
