Hi @RockerMan,

Are these the instructions you were following: https://docs.mattermost.com/install/smtp-email-setup.html?

Do you see any errors in Mattermost logs? What server version are you using?

Sorry, this is my fail
I remove quotes " in the parameters and it all worked

SMTP Server: smtp.mydomain.com
SMTP Server Port: 465
Enable SMTP Authentication: true
SMTP Server Username: admin
SMTP Server Password: mystrongpasswd
Connection Security: TLS
