Is there a way to stop Mail auto CC'ing yourself, when replying all ? In OSX 10.11 mail app if you "Reply all" it automatically CC's yourself. This seems to only happen when using reply all, but not when using reply. 

The setting under : mail > preferences > composing > automatically cc myself is disabled.

The preference is to keep a copy of an e-mail you originate or reply to one person or forward.  I don't see the point, since a copy goes into a Sent folder anyway.

Reply All means All people on the message, not just some.  If you don't want to keep a copy, just erase your name before sending.  Of course, there will still be a copy in your sent folder anyway.
