A user joe.smith@mycompany.net sends me an email. (this is their default reply to address also)
when i respond back - the reply to address is in this format
winnipeg.ca\joe.smith <winnipeg.ca\joe.smith@mycompany.net> and of course it bounces back with NDR
The e-mail address you entered couldn't be found. Please check the recipient's e-mail address and try to resend the message. If the problem continues, please contact your helpdesk.
Joe.smith@winnipeg.ca is another valid address for this user
So why does this odd reply to address come up when you reply to emails from this user?
