Pine is a program used for reading, sending, and managing electronic messages, designed at the University of Washington, specifically with novice computer users in mind, but it can be tailored to accommodate the needs of "power users" as well. Versions of Pine are available for various flavors of Unix as well as for personal computers running a Microsoft operating system. Pine supports IMAP4, POP3, NNTP, LDAP, ESMTP, SSL, S/MIME and MIME. Pine also includes basic filtering, scoring, roles and hooks for folders that allow you to manage your e-mail more efficiently.
