Thanks Kapil. That explanation helps.
These types of sigs are SO annoying on a public mailing list...
It's annoying to me to!!! The company where I spend most of my time started putting it on all emails going out from their firewall. I signed up for an external mail service to try and get around it only to find that they're doing at a the protocol level not at the mail server so it was still getting tacked on. I had to subscribe to a mail service that supports SSL connections. Now I connect to my mail server through an encrypted tunnel so the firewall can't touch it. I actually have to pay to get that damn thing off my emails! Unfortunately, it sometimes screws up. If Outlook can't connect to my mail server, it trys the company one. Something like that happened this time and that's why the email got posted twice. Sorry about that. Joe Goldthwaite
