complicated but fun, please help.

Okay here is what I have. I thought this was going to be a wham bam slam dunk. I need to update the poppasswd file on a Plesk system, I have it so the Plesk database gets updated, but I need to let people change their password from a web form, without having them need to login to the Plesk system. Where I am having problems at is when they need to update the poppasswd, which is a IMAP or QMAIL file. Plesk has files that will update the system, but it seems that I using the exec() and system() I can access those pl files. From the command prompt it works fine, html/php file doesnt work. Any thoughts? I would really appreciate the help, I'm doing this as a favor and would like to clear this off my plate. _________________________________________________________________ MSN 8 helps eliminate e-mail viruses.
