How to allow only select access to POP & IMAP

We are currently allowing access to POP & IMAP through both secure and non-secure methods. Because non-secure traffic is sent in clear text, we need to migrate all users over to secure POP/IMAP, but have many legacy systems that might not be able to move over. With that being said, is there a way to whitelist just the select few systems that need to stay on non-secure POP & IMAP?

Also, anyone have a good way to import the Exchange POP & IMAP log files, filter them, and only show the systems that are connecting via ports 110 and 143, in order to get a list of users that need to move to secure connections?

Thanks!
