  • 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.

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 !
