I cannot open Invoiceninja

Sorry, I have noticed that no emails are being sent. I have checked the login details, they are correct.

Mail options

MAIL_MAILER=log
MAIL_HOST=mail.xxxx.ch
MAIL_PORT=465
[email protected]
MAIL_PASSWORD=xxxxxx
MAIL_ENCRYPTION=ssl
[email protected]
MAIL_FROM_NAME=“Invoiceninja Admin”

Try changing MAIL_MAILER from log to smtp
