FollowMeEmail is based upon three open-source software packages: Fetchmail, by Eric Raymond et al, Procmail by Stephen R. Van der Berg et al., and the EMSD server agent by Neda Communications, Inc.
The NT port of FollowMeEmail would have been much more difficult (if not completely infeasible) without Cygnus Solutions' CygWin package. With CygWin we found it almost trivial to produce running versions of Fetchmail and Procmail on NT.
We're deeply grateful for the existence of all these tools and to all the people who've brought them into being.
