Pine (ver 3.96) Abandoned Freeware Pine is an IMAP Email Client developed by the University of Washington. This is the last version for DOS. Pine requires WATTCP (please configure the WATTCP.CFG file to match your system). Pine ships with a freeware word processor called "Pico". PICO.EXE can be deleted and replaced with a word processor of your preference. The MAILCAP.SAM file can also be edited to call other programs (such as image viewers) of your preference.
