Every time I send an email to one of my distribution groups I get a return mail .txrr (Road Runner) stating unable to deliver to the email address firstname.lastname@example.org. I do not have that email address in my Address Book nor can I find it on my hard drive in any file (hidden or otherwise) or as a key in my registry. Any one have an idea where this email adress is coming from? Only happens when I send a group distribution. Have sent through several different email servers using differnt email adresses with the same result.
