I am using the last commit and I have configured the SMTP settings like this:
Driver: smtp
Host: the host from my provider
Port: 465
Encryption: tls (I don't even know what to add here)
Username: the e-mail account
Password: password
Sender: the same address above
Now, there's no way to test if this works because every setting is saved and nothing is tested. But when I register the e-mail is not sent to the specified address, so I guess this is not working
