You can dump all of them as none of them were helpful. Thanks for all your help yesterday. Let me know what you want from Greenberrys. j -----Original Message----- From: Andrew Scott [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 17, 2002 8:18 AM To: CF-Talk Subject: RE: Web bugs, cookies and redirects... Jim you mentioned firewalls, I have only used the Norton's Internet Security on my home network. But it allows for me to stop certain information from being sent back, so this would be why I keep getting these blocked in my emails then (as I have told it not to send my email address), and yes this is always from spam mail, well at least that I have received anyway. -----Original Message----- From: Jim McAtee [mailto:[EMAIL PROTECTED]] Sent: Thursday, 17 January 2002 8:05 PM To: CF-Talk Subject: Re: Web bugs, cookies and redirects...
