Php mail program for receiving mails

[tentim]

I am familiar with php script for sending mails,but how do i go about making it
receive mails sent to an email address.I want to create a custom mail program
for a client such that a copy of every mail sent out will automatically go to the boss' email box which is easy.That means i av to shut out the mail program that comes with their hosting account so that staff wont use that.But now,how do they read incoming mails.

Or is there a way to configure squirrel mail to send a copy of every mail sent
to a specified email address?

[printf]

do it at the server level, most all servers have that feature (archive mail), on my mail servers, it creates a domain folder with folder dates and the username and all mail sent or received for that date goes in there.

/archive/domain/10122007/username/inbound/
/archive/domain/10122007/username/outbound/

But before doing that, check if it's legal to do that for your location.
