Hello, I can receive emails, but I cannot send any. When I try sending an email, it returns with the following message:
I saw another post on here that asked if they could telnet the IP that timed out, but the person didn’t respond. I tried on my computer and it works, but on the server it also times out. I can ping the server, though. Any ideas? Thanks.
If it helps, my mailcow instance is hosted at
And here is my cloudflare dns for mailcow stuff
