I tested this php form, and it worked on 2 out of three computers, all of which were on different networks. The one that didn't work stalled after I hit submit . . . all I got was a blank page . . . no error messages or anything. This happened whether it was on a PC or Mac, in Firefox, or IE. Any ideas what could be causing it? Thanks.

<?php
$domainname = "mydomain.com";			/**  Change this to your own domain  	  **/
$adminmail = "info@mydomain.com";		/**  Change this to your own email address **/
$webmail = "https://mydomain.com/mail/";	/**  Change this to your own webmail url  **/
$scriptlocation = "/home/ecreate";	/**  Change this to point to your script  **/

$name = escapeshellcmd($_REQUEST['name']);	
$username = escapeshellarg(escapeshellcmd($_REQUEST['username']));
$password = escapeshellarg(escapeshellcmd($_REQUEST['password']));

if (!isset($_REQUEST['name'])) {
?>

Code (markup):

I am using it with the following script to create new users, though I don't think this is the problem:

#!/bin/bash
emailgroupfolder=/home/emailgroup	## the folder in which you want new emailaccount homes to be created
emailgroupname=emailgroup		## the linux group to which your new email users will be assigned
useraddpath=/usr/sbin/useradd		## the path to the command useradd on your system (it's probably the same)

fname=$1
lname=$2
username=$3
password=$4
userlist=`cat /etc/passwd | cut -d: -f1 -s | grep $username`

enc_password=`/usr/bin/htpasswd2 -nb $username $password | cut -f2 -d :`

if [ $# -ne 4 ]; then
	echo "error6" ## There are more than or fewer than 4 arguments (Somebody has put down their middle name, or left off their last name)
	exit 1
fi
if [ "$username" = "$userlist" ] ; then 	## Username already exists on the system
	echo "error7" 
	exit 7;
fi
case "$fname" in
	*[!a-zA-Z0-9]*) echo "error2"; exit 2;; ## First Name contains illegal characters
	*);;
	esac
case "$lname" in
	*[!a-zA-Z0-9]*) echo "error3"; exit 3;; ## Last Name contains illegal characters
	*);;
	esac
case "$username" in
	*[!a-zA-Z0-9]*) echo "error4"; exit 4;; ## Username contains illegal characters
	*);;
	esac
case "$password" in
	*[!a-zA-Z0-9]*) echo "error5"; exit 5;; ## Password contains illegal characters
	*);;
	esac
/usr/sbin/useradd -m -c "$fname $lname" -d $emailgroupfolder/$username -p $enc_password -s '/bin/false' -g $emailgroupname -G 8 $username
echo "success"
exit 0
fi

Try this at the beginning of your script and see if there's any error.

error_reporting(E_ALL);

also some server will generate a file named "error_log". you can view this file to debug the script.
