>Hey. You're a genius. These days I discovered your routines for sending mails and I'm programming so that when an error occurs in my programs my clients don't have to note the error messages anymore (anyway they didn't. They're always very busy and very far from a pen and a piece of paper) Only a few of them has Outlook, Outlook Express or Windows Mail as mail client. Most of them are infected with "Hotmail" and "Gmail" and don't know other way.

Because they are not "system".
They are "environment" variables :-)
