I've just set up my new iMac, and I'm using Apple's Mail app. Every time I send a message, the message appears in my "Sent" mailbox (good) and is marked as unread (bad).
- I have selected "Inbox Only" under Preferences > General > Dock unread count.
- I have rebuilt the "Sent" mailbox (twice).
How can I stop my sent messages from being marked as unread?
