Hey! I just launched my own MailCow server, and it’s working well. I can send emails to iCloud and receive them without any issues, such as landing in spam. However, I ran an SMTP test on MX Lookup and could use some help. Could you please assist me? I got an WildCard SSL certificate on my domain.

You are testing the wrong DNS entry. You have to test mail.ckstudio.at instead, but it’s not reachable

    Have something to say?

    DocFraggle Hey, I Shut down my MailCow Server. Got some problems with my provider….

    So it is okey? I had to use the IP instead of the domain mail.ckstudio.at
    Shouldnt it work with mail.ckstudio.at also?

          cemesis Shouldnt it work with mail.ckstudio.at also?

          Yes it should work.

          cemesis I had to use the IP instead of the domain mail.ckstudio.at

          mail.ckstudio.at is not “a domain”. It is a hostname, a FQDN to be precise. Your mail domain (defined through the MX record) is “ckstudio.at”.
          That are 2 different things. Be sure you understand that properly, or you will have a hard time to properly run and configure your mail services.

                esackbauer Thank you! It’s working on both. I can send Emails and Receive them without any problems.
                What can I check also to be sure that everything works perfectly fine? Which MXLookUp Tests should I run? (Smtp and Blacklist is all right, what else?)

                I really appreciate your help! I’m kinda not sure even if everything is working fine.
