Mulberry is a high-performance, scalable, and graphically groovy Internet mail and calendar client. It uses the IMAP (IMAP4rev1, IMAP4, and IMAP2bis) protocol for accessing mail messages on a server, and the standard SMTP protocol for sending messages. It also does many things with MIME parts to handle mixed text and different types of attachments.
