• 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.

Question Customized firewall rules and fail2ban jail

O

OnsEns

New Pleskian
I find the firewall rules names quite confusing. For example, the name of SMPT: SMTP (mail sending) server. Does this mean the smtp ports 25 and 465? I want to create my own custom rules and have some screenshots with settings below. Are these the correct settings?

This is the image of SMTP port 25:

This is the image of SMTP port 465:

custom_smtp_port_465.png

And is it possible to open both ports in one firewall rule?

I'm also using Fail2Ban and it seems to me that I need to modify the plesk-postfix jail as well. Below the standard jail and the modified jail:

Will this work?
Thanks in advance !
