I have several machines running Mac OSX 10.2.3, and I have a problem that Mail.app behaves differently. Two machines want to save sent mails in the "Sent Messages" folder, while the other two in the "Sent Items" folder. I don't want to create two different folders on my IMAP server. How can specify the name of the folder where I save sent mails on the IMAP server in Mail.app?
