PHP implementation of SmarterMail API call

We need an API call from SmarterMail 7.3 implemented in PHP. What we are looking for is a single PHP file that contains all the code. We would like a function that we can supply: 1. SmarterMail administrator username 2. SmarterMail administrator password 3. The email address we want to change the password for 4. The new password for the email address in 3 We want a PHP function that will reset the password for the provided email address. We will not be providing access to our server for testing purposes, but the developer can download a free (and complete) copy of the mail server from <[login to view URL]> for their own testing purposes. Once the developer has finished and tested code, we will test this on our servers.
