ArGoSoft Mail Server is fully functional SMTP/POP3/Finger (Pro version also has IMAP module) server for Windows 95/98/NT/2000, which will let you turn your computer into the email system.
It's very compact, takes about 1-5 Mb of disk space (depending on the version), does not have any specific memory requirements, and what is the most important - it's very easy to use.
