Was smtp port 25 deactivated in latest mail server version 0.9.0 ?

Was smtp port 25 deactivated in latest mail server version 0.9.0 ?

The reason I'm asking is because the Domain DNS settings list is missing the SRV entry for port 25, plus I am not able to telnet anymore to the port 25. All the other ports are accessible.

This port is particularly relevant for https://mxtoolbox.com Domain Health Report, which cannot provide a complete report if the connection on port 25 is not working

The port is opened on the hosting system:

Hmm it seems to be my cloud provider who closed the 25 port.. Never mind.
