However, you can create a rule that will solve the problem for you: I don’t recall a way to delete sent messages automatically in Mail.
I don’t want all my old Sent messages from 1998!
I swear I used to be able to control how long my sent mailbox kept old sent messages-I’m sure I set it to 1 month! Now, however, I cannot find any pop-up or drop-down menus (like Junk Mailbox, which I have set to erase after one week). Macworld reader Chris want to take control of the message in Apple’s Mail, specifically the messages he has sent.
Email is one of those programs that you use, and then you realize that you have files dating back from a long time ago.
