[SOLVED] What are all these gmail errors?

[bearhntr]

New install of PVE 8.1.3 and fully updated. Today I was checking out the system logs as my system was rebooting and I was seeing all of these messages about gmail being unreachable. I never setup gmail on this install. I did enter my gmail.com address when I installed this - but never seen messages like this. Is something broken?

I have 'masked' my email address...and, yes my home network has IPv4 and IPv6 via pfSense router/firewall to Comcast.

The system likely tried to notify via the default notification target 'mail-to-root' about some event (e.g. finished backup). This target uses the local Postfix MTA so send the email to the mail address configured for the root@pam user - which is the address you have entered during installation.
Postfix will attempt to connect to the GMail servers on Port 25, but your ISP has likely blocked these ports to avoid their customers sending email spam.

Is something broken?

Not really, it's just that Proxmox VE will not be able to send you any mail notifications via sendmail/Postfix.

You could setup a SMTP notification target, which then can relay the mail to an external relay which is then in charge of delivering the mail.

Be sure to check out the official documentation regarding notifications: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_overview

Thanks - I will have a look at this. I will most likely want to setup e-Mail Notifications.
