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 mail.everly.page.

And here is my cloudflare dns for mailcow stuff

    Everly I tried on my computer and it works, but on the server it also times out

    If it doesn’t work from your server it’s probably some kind of firewall issue. Either you’ve configured your outgoing rules wrong or your hoster/ISP is blocking port 25 to prevent abuse. For example Hetzner Cloud servers by default block port 25 and 465 to protect from spammers. You can request to get the ports unblocked from their support.

        Have something to say?

        D4niel I’ve disabled the firewall to see if that’s an issue. I also have another instance of mailcow running on another server from the same provider and it works fine. I could contact them to see but I don’t think that would be the issue.

          Telnet from your pc to your server on port 25 and check if it timeout too

            What is the rest of the message after

            If you do so, please include this problem report. You can

                           The mail system

              Sorry, i got confused. Can you send an email from this box to maybe a gmail or hotmail address and see if it gets delivered

                luchris I’ve tried doing that and it gives me the same message

                  You mentioned that you have another mailcow box correct? Can you try sending a test to the working box. Then check the postfix and rspamd logs to find out what is wrong?

                  If you dont even see the connection, then most probably your provider is blocking outgoing on port 25, but allows incoming on the same port
