mail notification problem

[og900aero]

Sending an email doesn't work overnight (only a Debian 11 security update since). The error message is as follows: terminated with exit code 36, output: mail: cannot send message: Process exited with a non-zero status

If I try to send an email with the mail command itself, the same error occurs. I realized something important thing:

Bad: echo "Teszt" | mail -aFrom:[email protected] -s "subject" [email protected]
Good: echo "Teszt" | mail -aFrom:[email protected] -s "subject" [email protected]

So if I use a full hostname, it doesn't work, if it's just the domain, it's good. I don't understand what has changed since Friday last week besides the Debian security updates.

Hi @og900aero it was actually an entire version update, buster to bullseye . I'll see what I can find out.

I installed it from sources 1 year ago:

/etc/apt/sources.list.d/bullseye-icinga.list
deb https://packages.icinga.com/debian icinga-bullseye main
deb-src https://packages.icinga.com/debian icinga-bullseye main

It work until May 21, and update debian:
/etc/var/log/apt/history.log

There's a theme selector in the options if you don't like the new defaults 😃

still trying to find some information, the mail command is from the standard Debian package

I know, but the usual old theme is not there. Only dark and light, but but none is the same as the old one :)

How about some of the extra themes here: https://exchange.icinga.com/search?q=tags%3A%22Theme%22&page=1

could add them in using a volume
