One of our user has that problem. Since few days in his inbox folder began appear sent mails. Could any one give me any suggestion how can i get rid of that?
Subject: send and file
It sounds like your user is hitting “send and file” then Enter, when sending a message. “Send and File” brings up a dialog for you to choose a folder. The default is the top folder - which is the Inbox.
Your user should be instructed to simply use the “Send” button. A message which is saved when sent will automatically show in the Sent folder.
They may also want to adjust their choices in File>Preferences>user Preferences, Mail>Sending and Receiving. They can choose to automatically save all sent messages, not save any sent messages, or be prompted each time.
