In Mail>Preferences>Composing I have the box labeled "Automatically Bcc: myself" checked. It used to do that but stopped a few weeks ago. I thought it might have been due to changes in my Gmail account but I went back into that via browser and did not see anything that I thought would be wrong. In Mail>Preferences>Accounts>Mailbox Behaviors>Sent the box for "Store sent messages on the server" is checked. I tried un-checking it and sent a test message to my secondary account on Yahoo but no luck. This is frustrating. I am not sure about timing of this problem vs the update but I recently did a minor upgrade in Lion. Currently Lion 10.7.5 and Mail 5.3 (1283) Any help appreciated.
