  * Advanced IMAP client supporting SSL encryption and SASL authentication.
  * POP3 support.
  * Mailbox threading (both strict and non-strict).

    examples.
  * Handles MMDF, MH and Maildir in addition to regular mbox format.
  * Messages may be (indefinitely) postponed.
  * Colour support.
  * Highly configurable through easy but powerful rc file.
