Yes, that's how Maildir mail works - delivery to a Maildir folder means
that the mail is put in Maildir/new until it is seen, when it is moved
to Maildir/cur via Maildir/tmp - it's complicated, but it's necessary
in order to maintain appropriate locks on the files when multiple
clients are accessing them.

When you say "can't login" - what is the error?

What do the dovecot logs say? You can see where dovecot logs to by
looking in /etc/dovecot/conf.d/10-logging.conf - can you see your
roundcube install attempting to authenticate?
