Writing a mail server

[Lee Phillips]

I am thinking of writing a shell script that auto-replys to incoming
mail messages with certain subject headers by mailing a file to the
sender -- you know, a mail server that people can use to get certain
files.  It should also keep a log of who got what.  I'll bet there
already is a tool like this out there, though, and I won't have to
write my own, right?
