Install poppassd.

Include the class above within your php program and then use:

$p = new POPPASS;
$p->NewPass("host.domain.com",106,"fred","oldpass","newpass");


Thanks to Manuel Lemos for the original POP3 class that  I modofied to
create this. (You're welcome Andy)

Hope this helps
Cheers
Mike
