This extension has been moved from PHP as of PHP 4.3.0 and now
vpopmail lives in PECL.
There is a more robust version of this extension, and other goodies for working with vpopmail from PHP available at: http://pmailadmin.sourceforge.net/
The extension will get added back to PECL once it is finished and tested.
If you set vpopmail up with mysql support its quite easy to get a full listing of domains/users. You'l only have to use the vpopmail php functions to add/delete users/domains in a own written front end.
In reply to "You can easily save the directory listing of ~vpopmail/domains"
This would only work if you had 100 domains or less. After that, domains are broken up into directories. Vpopmail will not put more then 100 domains in a directory because it's not efficient.
Well, you can safe your qmail-data like the domains, etc. in a database, which is quite usefull in my eyes. You just have to keep the data synchronized.
This library is kind of useless without key functions like get_domain_info() and list_all_domains(). You can add and delete virtual domains, but you cannot list or view them. Without such functionality you can't go and write your own PHP front end to qmail.
