• 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.

SMTP - Can't connect from Outlook/IPhone E-Mail Client

New Pleskian
Hey community,

i've a server with Cent Os (Installed today - nothing else installed but Plesk 12.5)
I installed Plesk 12.5. on a clean, updated system.

Now there is a little problem:
I added just one email-address to check functionality.
All works fine but I can't connect from external clients.

Plesk installer has installed:
Postfix - SMTP - Connection with problems
Dovecot - IMap - Connection successful - No problems getting emails on my IPhone


I tried to connect via Telnet. (Port 25)
It was successful to connect via port 25 - but there is no chance to connect via a client to port 25.
Port 587 gives me no chance to connect to.

What is going wrong? I think there is no firewall blocking.

Hope you have a solution.
