Console Reports Firewall Closed Despite UFW Active

[Michelangelo]

Hi everyone,

I recently set up my Linux server for running MTA, and everything was working fine until recently. Today, I noticed that the console reports that certain ports are closed due to the firewall, even though running ufw status confirms that the firewall is ok and allow por.

Has anyone experienced a similar issue or can suggest what might be causing this discrepancy? Any insights or troubleshooting advice—from checking firewall configurations to potential issues within MTA—would be greatly appreciated.

Thanks in advance for your help!
