Seeking App for Non-Cloud Email with Folders and Filters

[toolworker]

Is there an Android email app that will do the following:

• Sync with multiple POP3 accounts
• Sort mail into folders automatically
• One of the sort criteria: Sender is in my Contacts list

If not, would someone please write it?

(I can't switch to IMAP and I won't use Gmail or another cloud-based service.)
