Hi!
I just tried to set up my first imap account (fastmail.fm).
When I check -> the emails are not listed (downloaded) in the listview.
The status says: successfully connected....but the the listview
stays empty (the logfile too).
The IMAP plugin only delivers unseen messages. This is because with IMAP you usually leave all your mails on the server, which eventually results in a large list of messages that PopMan had to retrieve and show each time. Therefore it makes sense to only retrieve the new "unseen" mails with an email checker/notifier like PopMan.
