Hello. I have installed this script to have my spam emails be learn automatically and deleted after 30 days. It seems to be running fine except that it is not deleting the emails after 30 days.

I've tried emailing the original author but I am not getting a reply. If it is not too much to as, can someone tell me where in the script it is to have emails be delete after 30 days as stated in his blog?

Here is the script.

Here is the details.

Any help would be appreciated. Thank you.
