abrt-server sent an email to root@localhost, but there are no updates in var/mail/root

I'm debugging an issue with python and incron, when I run my script, and then checking the status, it says it has an error. then it said it sent an email to root@localhost, I'm assuming this is at /var/mail/root? When I check that file though, the last update was 10 days ago. Now I'm not sure where I should look for the detailed error message
