I was inspecting the syslog after the OMV5 upgrade, and the only task which is giving errors is the postfix/smtpd service.
In OMV4 I got all the notifications working (plus a telegram channel to replicate them with a bot), but in OMV5 I cannot make them to work, except the "Your user account was used to log in to the openmediavault control panel via a web browser" which works like a charm.
I have the SMTP settings well configured (smtp.gmail:587, username without the domain and password) as the login email gets sent correctly. But the rest of notifications (disk resources, cpu usage, smart...) does not get sent.
I tried to reinstall and restart postfix, and clean, save, fill in and save the notifications dialog in the GUI.
These are the errors related in syslog:
Thanks in advance.
