Easyblog not Pushing Subscription Emails

This client is having issues with their site sending out subscription notifications for their blog. In fact, it doesn't appear to be sending notifications at all.

The cronjob is setup and setup correctly, and as far as I'm aware the settings are set correctly, however it refuses to send out emails. Based on the mail activities section of Easyblog, nothing has been sent out since last Friday when I subscribed to their blog.

I double checked this on the server by checking the mail reports there, and I'm seeing the same thing.

Could you take a look and see what possible issues could be preventing the site from sending emails? I've attached site and FTP credentials to this ticket for you.
