Features of using native PHP code for vmailmgr.

- No need to compile PHP module, which few find themselves able to do.

- Fully up to date as of 0.96.6, able to make use of all the new
  functionality added (multiple forwarding destinations, users with forwarding
  destinations and mailboxes, etc.)

- User parsable listdomain output. Listdomain can be arranged however the
  admin likes, allowing fields to be left out, reordered, or new fields
  added (like a delete button).

- Multiple commands per script, and user parsable output. While the python
  CGI allows user parsable output, only the PHP functions can call more than
  one function from the same page.

- Only the PHP functions offer proper handling of multiple forwarding
  desinations, allowing you to expand the number of fields on the HTML form
  depending on the number of forwarding accounts already existing.

- Easy to use interface, with good input checking. PHP commands are very
  similar to the command line commands, and can accept all sorts of bad data
  from user forms. New conditional failures can be easily added.
  
- Easily modified. The PHP commands are easy to add, extend, modify,
  combine, update, etc.
