IM (Internet Message) -- mail/news handling commands and Perl modules


IM provides a series of user interface commands (imput, imget, imls, ...) and backend Perl5 modules to integrate E-mail and NetNews user interface. They are designed to be used both from Mew version 1.x and on command line. Mew version 2 or later is independent of IM. Still, the immknmz command is useful for Mew version 6.x with mew-nmz.

The folder style for IM is exactly the same as that of MH. So, you can replace MH with this package without any migration works. Moreover, you are able to operate your messages both by IM and MH with consistent manner.

Mail/news messages are dispatched by way of SMTP/NNTP and are retrieved from local mailbox (mbox file, Maildir, MMDF file, MH folder), POP3 server (plain password, APOP), IMAP server, or NNTP server.
