[SOLVED] email notification not working (PMG relay inside)

[atec666]

Hello,
I setup email in Datacenter \ options
But my proxmox node can't send mail to proxmox mail gateway.
i test with telnet <ip_proxmoxgatewxay> 26 => and it's ok (can send mail etc for email@example.com without issue)

But proxmox can't why ?

Note : echo "test from cluster" | mail -s "test" email@example.com (with root user bash/tty)
i can see : tail -f -n 25 /var/log/mail.log

With : echo "Subject: sendmail test" | sendmail -v email@example.com
same issue with postfix/error message in log ...

In fact when installing Proxmox on top of Debian Stretch i choose "local delivery" for postfix config.
I just run :

• dpkg-reconfigure postfix and choose "internet site",
• nano /etc/postfix/main.cf and add : relayhost (and smartrelayhost)

sending work (with mail command), hope that Proxmox will do the same.

Did you get this to work?
I am having something similar, but I find when the Proxmox servers are in my homelab, the email notifcations get blocked. When installed physically in the office location, it is sending... But I get that similar error about status bounced
