I have set up 5 email addresses in Apple Mail, all is ok apart from one. I am not being allowed to delete messages from the inbox. Every time i try to do this a box drops down with this message. The destination mailbox "Trashfirstname.lastname@example.org" does not allow messages to be moved to it. Also i have the same duplicated emails in the trash folder and i cannot move any of these into the inbox and get this drop own message. The destination mailbox "Inboxemail@example.com" does not allow messages to be moved to it. I have a second MBP set up this address with the no problems. Can somebody help out wit this problem please.
