• Our team is looking to connect with folks who use email services provided by Plesk, or a premium service. If you'd like to be part of the discovery process and share your experiences, we invite you to complete this short screening survey. If your responses match the persona we are looking for, you'll receive a link to schedule a call at your convenience. We look forward to hearing from you!
  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

    Issue Cannot connect to mail-tester.com

    Hello meregha, I actually gave it up after trying every possible thing I could think of; everything was positive!! When I saw your post, I tried it and it worked. I cannot explain it but it looks like leaving it for a while might resolve the issue.

    Issue Cannot connect to mail-tester.com

    Really sorry for the delayed response -extraordinary circumstances (: Firewalling? I did disable the firewall without success. The strange thing is that it used to work,; emails were sent to test-mailer.com without a problem. This problem appeared out of the blue. The webhost Support team...

    Issue Cannot connect to mail-tester.com

    Apologies for the late response (health reasons). The service provider insists they haven't blocked us. I believe them and there is no reason for them to do so when we can email all others. We have tried every thing we can think of without success. - disabled firewalld - uninstalled...

    Issue Cannot connect to mail-tester.com

    Thank you, john0001, for your advice. I tried traceroute from another server that works, as you said. But I couldn't catch the red herring .. my knowledge of networking is minimal. This is it:- # traceroute 94.23.206.89 traceroute to 94.23.206.89 (94.23.206.89), 30 hops max, 60 byte packets...

    Issue Cannot connect to mail-tester.com

    Is there a diagnostic utility that would yield the exact cause of "connection timed out", for example: firewall / IPTables / Postfix? In our case it looks like "server-related", our server, not the destination's, because "traceroute" doesn't even pass (192.168.0.1 (192.168.0.1), the rest are...
