Using Leopard and Mail. Under Trash I have 'POP Account' and 'On My Mac' When I select a message and press delete I get a warning saying: The message ... could not be moved to the mailbox Deleted Messages POP Account The destination mailbox Deleted Messages POP Account does not allow messages to be moved to it. I can drag a message to the 'On My Mac' folder and select delete and this removes the email - but seems wrong. This is my first mac (first day), im used to a deleted message going to a bin which you choose to empty as and when. Can anyone help me out how i should be deleting emails? Thanks!
