Ater seeing Grimz post, i'm curious..have you gotten any replies by email?
Do you mean clicking on email all replies to my real email addy on a post? I havent tested it, so im not sure what/if overrides a specific post change vs your settings, or if it works to begin with, but what are your settings in My Home/main configuration/Subscribe - Unsubscribe from receiving forum posts by email, change message notifications? Click on edit beside that line to check. If you meant that you set it up originally to have stuff emailed to you, you can change your choice there at any time.
/me wanders off to test email reply thingies
