[tclug-list] need help removing old files and directories

[Raymond Norton]

I need to remove old directories and files from 
/var/spool/Mailscanner/quarantine

The following command gets rid of the files, but not the directories. 
What flag would I need to add to accomplish this?

find /var/spool/MailScanner/quarantine -mtime +10 -type f -exec rm -rf {} \;
