• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Unable to send email to certain domains

JasonBibby

New Pleskian
We've been having this problem for a while, email sends fine to 90% of our clients however for a small selection the email won't leave the mailbox on any computer in the office, clients are also having problems on different domains to different email accounts

I get the following error in Apple Mail, along with the rest of my clients using other mail programs.

"Cannot send message using the server xxx

Verify that you have addressed this message correctly. Check your SMTP server settings in Mail preferences and very any advanced settings with your system administrator"

Anyone have any idea why we can't send to certain domains? My main question is why isn't the email leaving my mail account? What's causing it to not even leave? I don't get a bounce back or anything on the log as it won't connect to the server.

Any help would be appreciated.
 
Try to troubleshoot it with help of investigation of main Plesk maillog /usr/local/psa/var/log/maillog
