s-nail

Send and receive Internet mail

S-nail provides a simple and friendly environment for sending and receiving mail. It is intended to provide the functionality of the POSIX mailx(1) command, but is MIME capable and optionally offers extensions for line editing, S/MIME, SMTP and POP3, among others. S-nail divides incoming mail into its constituent messages and allows the user to deal with them in any order. It offers many COMMANDS and INTERNAL VARIABLES for manipulating messages and sending mail. It provides the user simple editing capabilities to ease the composition of outgoing messages, and increasingly powerful and reliable non-interactive scripting capabilities.
