E-Mail notifications

[upcnuwft]

Hello everyone,

I configured Postfix to send e-mail notifications over an smtp relay host.
Everything works fine so far, but I have some additional questions.

To change the sender e-mail address I did the following:

# /etc/postfix/sender_canonical
root mail@provider.com

postmap /etc/postfix/sender_canonical

The sender now appears as root <mail@provider.com>.
I wonder if I can change the "root" part to something else?

And one more question:
I do receive e-mails for backup jobs, but not when system updates are available.
Is there such an option in Proxmox that I didn't found? Or am I supposed to use apticron for that?

Thanks in advance!

is the pve-daily-update.timer active?

systemctl status pve-daily-update.timer

Thanks for the hint.
From my understanding it sounds like I could use smtp_header_checks instead of sender_canonical_maps.
But it seems that this is not the case. I actually have to use both for it to work, otherwise I'll get 530 Sender rejected.

One thing is not clear to me. He wrote:

Don't forget to run postmap on the header file

Does that mean I should run postmap on /etc/postfix/smtp_header_checks?
I didn't do that... and it seems to work.

is the pve-daily-update.timer active?

Yes it is. I'll keep an eye on it.
Let's see what happens when the next update is available.

Today I looked into the web interface and there were two updates available.
I didn't receive an e-mail notification about this!

This is a new installation. I didn't change anything special.
So I assume this functionality doesn't work out of the box?
