I have migrated my POP accounts to IMAP. What a nightmare! Now I'm trying to recover mails from my old account, since I lost my "sent" mails during the process.
Before migrating, i moved them all to a mailbox which I created, called "sent_archive". When I access the mailbox manually, I can click on each file and an Email opens. So they're there. I can see them + open them. Whenever I try to import them and choose the mailbox during import, the mail-app. tells me "No valid Mail for Mac OS X files were found". What's going on??? How can I fix this? Thank you for your help!!
