Noob on PostFix : how to get email notifications ?

[Bristow]

Hello to all,

I have 2 proxmox servers and I would like to enable email notification on these 2 servers.
My network is very simple and I have a working stmp server.

I have activated in /etc/postfix/main.cf the relayhost to smtp.ac-lyon.fr. But if I do
echo "mail test" | mail -s "proxmox" my@mail

I get the following error:
send-mail : account default not found : no configuration file available.

What can I do ? Thanks in advance !

* please post the journal (especially the logs from postfix) when you run the test.
* else - in general - running `dpkg-reconfigure postfix` should guide you through the setup - and there you can add your smarthost

I hope this helps!

sorry for the delay. I seem to have a problem with postfix:

root@pve1:~# dpkg-reconfigure postfix
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset),
    LC_ALL = "fr_FR.utf8",
    LANG = "en_US.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to a fallback locale ("en_US.UTF-8").
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
/usr/sbin/dpkg-reconfigure: postfix is broken or not fully installed
root@pve1:~#

not sure what to do... Thanks!

I found solution.

Fix locale :

locale-gen fr_FR fr_FR.UTF-8
dpkg-reconfigure locales

Install postfix (not installed ) :

apt install postfix

Configure postfix

dpkg-reconfigure postfix

Reload service

service postfix reload

Test ok with

echo "mail test" | mail -s "proxmox" my@mail
