I have been using TWIG (http://twig.screwdriver.net/) for some time now.
Though it has much more than just Web Based Email (with IMAP/POP3
group/Calendar/Notes/forums etc) you can configure it to select just
what you want. It is pretty fast too! My server is a Celeron 433 machine
with TWIG+MySQL+APACHE+IMAP and it works wonderful. I have had no
problems or crashes since I installed it.
There are many others too: aeromail, bobomail, acmemail to name a few. A
search on Freshmeat/Sourceforge will show you more!
Hope that helps
