How to stop mail app from sending me an e-mail with "reply all" When I want to do "reply-all" to a message that involves multiple people, the mail app includes myself in the list of recipients. Is there a way to turn off this feature?
Like Tyson said, normally this doesn't happen, but maybe your Mail.app is configured to send you a copy of your mails sent.  

Go to Mail > Preferences > Composing and see if you have "Automatically Cc (or some other selection) myself" selected and unselect it if you do.
