Issue Wrong "From" in system notifications

[IT Ufficio Key-One]

Server operating system version

Almalinux 8.10

Plesk version and microupdate number

18.0.61 #5

Hi, I've recently installed some VPS with Plesk on Almalinux 8.9 (now self-upgraded to 8.10).

I've noticed that all system notifications (i.e. watchdog, scheduled tasks..) are sent from a wrong "From" (i.e. watchdog@<somefakenamewithunknownipaddress>.plesk.page instead @Full-server-hostname).

As a result, all system notifications are received as spam.

The full server name is correctly set under Server settings and correctly reported by hostnamectl command.

Where should I check further?

Thanks.

Does the output of grep "hostname" /etc/postfix/main.cf show your new hostname?
