CWP Delete deleted emails, automatically

We know that a big problem with full disk space is because the person deletes the emails, BUT DOES NOT CLEAN THE EXCLUDED BOX.

Is there any way to create a CRON Job where it deletes all deleted emails?

I just found this code below. But he deletes it from the inbox, and he has to manually add the domains.

Is there a way to automate this when creating the hosting?

Code: [Select]

15 2 * * * /bin/find /home/account/mail/domain.com/user/new ! -mtime -30 -type f -exec rm {} \;

Hello we didn't delete any user file so delete commands are not included.
