Hello,

You will find the documentation here: https://docs.centreon.com/fr/docs/administration/postfix/

Merci, c’est cette documentation que j’ai utiliser mais quand j’envois mail test ça ne passe pas.

Can you confirm that emails do come out after this step

https://docs.centreon.com/docs/administration/postfix/#testing-and-troubleshooting-email-configuration

echo "Test" | mail -s "Test" user@isp.com

oui! pourtant mon postfix est bien active 

anything in the logs?

tail -f /var/log/maillog

voici l’erreur qu’on m’envoit

@dakombaye 

• are you behind some firewall?
• do you need a proxy?
• do all hostnames resolve? (ping)
  • destinationdomain.com
  • smtpdomain.com
  • otherexample.com

oui le ping pour tous les hôtes passent très bien.

Gmail has some restrictions on external app access since May of this year. Follow this article instead; it walks you through the setup on Gmail side, setups like creating an app password and so on.
