Email Config
It is hard to set this up.
There is no page to input this in a gui.
It is all done in the localsettings.php file in the software.
The settings in the file are ok but to use secure email you need one trick.
$wgSMTP = [
'host' => 'mail.example.com', // could also be an IP address. Where the SMTP server is located. If using SSL or TLS, add the prefix "ssl://" or "tls://".
