Hotmail like script

[Haze]

I have a client looking to implement a service similar to Hotmail. Does anyone know of an existing script that will do this?

[is0lized]

doed he want users able to sign up, or does he want to sign them up himself?


also, what language?

He, wants them to be able to sign up. So far I have found these:

http://webbasedemail.com/index.ehtml
http://buildacommunity.com/autoemail/#
http://www.emumail.com/
http://www.gossamer-threads.com/scripts/webmail/index.htm
http://alias-mail.com/

Anyone have any others I can take a look at?

As for language, perl or php is fine, they have no prefferences.
