xbilling is not sending emails

[zustudios]

The module xbilling is not sending emails.
 
Roundcube is sending and receiving emails just fine.
Is there a solution to this problem or do I have to use the billing module?

I installed this module on a fresh sentora installation and emails are working as expected from xbilling.

What does your mail log say?

I stopped using xbilling because of this. I will try again and let you know. I installed the regular billing module although I'd rather use xbilling.
