My external IMAP account is playing up in mail. the mails I have sent are no longer appearing in the main 'sent' folders, but are instead finding their way into sub-folders within the account inbox, and it seems to be creating new folders every couple of days. So, if you go into inbox - IMAP account inbox -, there's a drop down to subfolders as follows: deleted messagess drafts inbox deleted messages inbox deleted messages sent messages sent messages and on and on and on... Does anyone know why this is happening, and what I should do? Thanks in advance, emer.
