Sentora not sending new user email

[pomtom44]

Hey all

Iv spent the past few days setting up sentora and finally got it working
But when I went to make a new user, either though Xbilling, or though the control panel
no email gets sent

I have dug around all the logs I can find, and messed around with different settings, but cant seem to get anything to work

Im not sure what information you will need, so ask me for screenshots or log files.
But any help trying to get this to work would be great

Thanks in advance
Tom

After finding a logging option I managed to find this in /var/sentora/logs/sentora.log
Error sending email (using sys_email):

found Sys_Email in core/dryden/sys/email.class.php
but found that it should log the error as well, but its not.
So no idea where to go from here
