Hi there :)
This project is one of my first bash scripts I have ever written.
When I read the script minutes ago I got some heavy goosebumps since this is a total crap :D
Hopefully I will have some time to fix the script.

Back to your issue:
Can you check you /var/log/ directory for mail files?
I think /var/log/mail.log only exists on Debian Servers.
