Popper is also a web based POP3 (Post Office Protocal) client. It sits on the server and talks to Apache and MySQL, allowing anyone with your (hopefully non-guessable) password and account name to read your e-mail with any CSS enabled browser on the internet. Awesome for people that access the web from different boxes everyday, not a good idea for people who use '31337' as their password.

This GPL'd program (perhaps script would be more accurate) is written in PHP4 and includes the following features (as expected of any mail client):
  • multiple POP3 server support
  • compose/reply/forward/send support
  • html-written email viewing support
  • an address book
  • a calender
