Notice that I called the function .._auth_module(). If you want to separate
websites from accessing vpopmail on your box you need a fundamental
authorization that allow you to perform vdeldomain(). More descriptive
//Your'e a super admin and can manipulate domains and users
$rst=vadddomain("myname.tld","postmaster_pass"); //or whatever is the
echo "domain created";
//your regular user that can only auth himself via
on vpopmail_auth_module() level there would be a something like "sudo"
mechanism performed so that all functions that require phisycal access to
vpopmail dir structure were run as authorized super user (or any other user
that has some limited permissions.
Personally I feel, that could be an extension to vpopmail itself. A module
for PHP operations that would introduce some levels of admins etc...Imagine
that you can assign a user rigths to create 5 doimains...
Bad thing is I am no coder. All of above is just my imagination and
theoretical issues. Perhaps someone of vpopmail users is quite a PHP geek
and could verify if it has chance for a success.
