creation and listing of email accounts

[themarty]

i'm creating a web-application and would like to be able to create email accounts for the domain under which the app runs.
I'm looking like crazy for a comprehensive manual that explains how to create an email account and - more importantly - how to list the current accounts (and change them if necessary). If i know the linux commands i could write a php-script that executes them.
So far i've only been able to find little bits of the puzzle here and there, but nothing i could piece together.
Does someone know a good tutorial or manual where this is explained?

Thanx in advance!

p.s. postfix is installed on the debian server
