(Vendor Independent Messaging
) was a standard API
for applications to integrate with e-mail
on Windows 3.x
, proposed by Lotus, Borland
in the early 1990s. Its main competitor was Microsoft's MAPI
, which was the eventual winner of the MAPI v. VIM war. Ultimately, the choice of VIM or MAPI did not make a huge differences: bridges meant that an MAPI client could access a VIM provider and vice versa, and the rise of Internet e-mail in the mid-1990s rendered the panoply
e-mail systems which VIM and MAPI were meant to cater to largely irrelevant.
