I am looking for a Browser based email program that will allow my users to check there pop accounts email from the browser anybody know of such a thing that don't cost and arm and leg?

You can find some excellent PHP/MySQL based web-based POP3 programs at http://www.hotscripts.com/PHP - particularly look for SquirrelMail.

I've got to second that. Give SquirrelMail a try and see if you like it - http://www.squirrelmail.org

Free, excellent.

I've been using IMail from http://www.ipswitch.com
it seems to do the job for us.

If you are interested, I do have a friend that has a fairly
new version that he would sell. Its the FULL Unlimited version, he got it with the purchase of a server from one of my customers and I know he doesn't need it and never will.
