Please could you guys help me. I successfully configured the dockerized mailcow using the Ubuntu Liveserver running inside my Vmware (note: I have a static and dedicated external IP for my network). Each step was successful and I added my domain behind cloudflare, added the MX records correctly and also added the DKIM.
I configured the SoGO client and added my domain and I sent out an email which was successful. b
But
I cannot receive emails. When someone sends email to my email address it shows sent but after some days it bounces back with a error message from gmail.
So I telnet my Postfix from an external IP address and I got the following;
C:\Windows\System32>telnet 31.2..* 25
Connecting To 31...**…Could not open connection to the host, on port 25: Connect failed
Is the above error the reason why I can send emails to gmails but I cannot receive emails. Please help
