Deleting email from the inbox - POP3

What is the proper way to delete the processed email from the POP3 inbox? I"m using the example for "Processing multiple messages using POP3" from the help file. I have set filter.AllowInboxDelete = true; but the emails remain in the inbox after processing. What do I add to the filter_processed method to delete from the inbox?
