    I fixed this by removing the return_path directive from the remote transport

    This turned out to be an issue with the POP3 Server of my ISP (I think is
    Microsoft Exchange). The failing message had a single "." on a line in the
    middle and was not being escaped. Fetchmail thought it had an end of message
    and then failed to get into a proper protocol dialog because the server was
    still sending the end of the message. Issuing the QUIT command and closing
    the connection meant that the POP3 server did not implement any of the DELETE
    commands it had received. Next poll by fetchmail the whole thing repeated.

    Slowly the messages built up.

    I eventually cleared it manually by using telnet.
