mRpostman provides multiple IMAP (Internet Message Access Protocol) commands based on the RFC 3501 manual (Crispin, 2003), its updates, and other related documents. The goal is to make it easy to connect to your IMAP server and execute commands such as listing mailboxes, searching and fetching messages in a tidy way.
