PHP Mail forwarding script

[Canuckkev]

Okay, I think I want to set up and anti spam email service. I have access to a pop3/smtp server. I want users to be able to sign up, then set up email forwarding and filters. Not storing the messages, only forwarding them, and filtering (also, preferably the ability to bounce messages based on the filters).

Now, I don't know how to go about doing this. There are mail programs such as SquirellMail at hotscripts, but does something like that give me the ability to not allow any space for a user?

Also, would there be any issues setting something like this up with my host (myacen)?

This is quite dependant on what incoming mail server you are using -- sendmail, qmail, or exim (my favorite). Your scripts would then have to edit configs, etc or however your choice of mail server worked.

You'd also have to config your IMAP and POP3 servers to work with this configuration.
