mail-sources is

       ((imap :server "localhost"
              :port 1143
              :user "winkler@foo.com"
              :authentication 'login
              :predicate "1:*"
              :mailbox ("INBOX" "JUNK EMAIL"))
        (pop :server "fencepost.gnu.org"
             :port 995
             :user "winkler"
             :authentication 'apop))
 
Server is "localhost" because I am using davmail in between emacs and
the actual IMAP server (Office 365).  There is no problem with
fencepost.
