• The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is 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.

Issue with mailing lists - limiting concurrent connections to hotmail

Hi,

We have a problem with mailing lists, whenever a user sends out a mass email to 1000+ email addresses, quite often we get bouncebacks indicating that to many connections have been made to the hotmail servers. We have our concurrentremote set to 30 in /var/qmail/control, the issue is if we lower this to say 5 delivered mail will become delayed.

Has anyone else experienced this? Quite a few of the larger email providers are limiting the amount of connections, so if you try and send an email to 200 hotmail addresses at once chances are half of them will bounce back.

thanks
Stephen
