[MODULE] xBilling

[Fuzzy]

I have xbilling working good so far with testing.I just have one major problem.xbilling wont send any emails.Can anyone tell me the solution?
centos 6
sentora 1.0.0

 I know the free packages don't send emails...anyone else confirm this? 

Also a quick question, the ipn url is the ipn_listener.php right?

I just installed sentora 1.0.3 on centos 7 I will let you know if the mail works for xbilling.

I can confirm that mail does work in xBilling as I just installed it on a fresh sentora installation and I am receiving mails.

Did you Install it without making any changes except changing it from zpanel to sentora? I reinstalled sentora like five times and xbilling is still not sending emails.Everything works but the emails roundcube is working.
No one that had the email issue or staff has posted any fix to the problem.I can't use sentora until I can fix this issue.I've been trying to figure this problem out for like 2 months now ON MY OWN.No one seems to have a solution or at least they haven't posted it.

I know this sounds simple but you never know, have you checked that the mail just isn't received into the spam folder?
I know when I was testing it for some reason mails sent manually, via roundcube or a mail client, were going straight into the inbox but mail from automatic stuff ie. xbilling were going into the spam folder.
