Issue Mails not receiving

[wildnis]

I'm not receiving my mails. I read pretty much every post here in the forum.
Port 25 is open and I ran a test with checktls and everything seems to be fine (but a certificate issue which I got no idea why).

I wonder if anyone can help me. I'm new to Plesk and must say that I'm getting pretty frustrated...

Thanks for your help

Well, a couple of observations:

- your mail server responds as server.hickerpublishing.com, but that domain name doesn't have a "A" DNS record
- the IP of your mail server has no PTR record
- your mail server is using a self signed SSL certificate
- the MX record of your domain orca-gallery.com does point to the IP of your mail server, as it should
- your mail server accepts mail messages and the info<yourdomain> address exists.

Looks like a DNS issue. Your server needs some additional configuration in order to be operational, but basically the services seem to work.
