It depends what MTA you're using.  I just poked with Postfix, which
came with Ubuntu on my laptop, and sent a message to svlug just now
describing most of what you need.  About three lines of configuration
will give you a virtual domain that delivers all mail to the standard
input of a specified command.

Every MTA has its own documentation.  Sendmail's, for example, is a
heavy O'Reilly book that inspired jokes about whether you start to
mumble "defocus" in your sleep.

I feel skeptical of using PHP for this application, because I associate
it with web scripting and not with general-purpose programming.  But it
_is_ Turing-complete...
