Mailbox Sweeper
Mailbox Sweeper is a Java application that lets you connect to your mailboxes and preview the Subject lines, sender and size of the messages stored there. You then can decide to delete single/multiple selected messages or delete all messages at once. It is especially useful to completely clean out spam ridden mailboxes, deleting big attachments or to sort out unwanted emails while they are still on the server and then download only the emails you actually want to download.
