Well, I'm out of ideas at this point. It looks like you may have to
modify SMTPDirect.py and add some debugging. You could try sprinkling
calls of the form

    syslog('smtp-failure', 'some format string %s and %s', var1, var2)

in various places to try to get more information. For example, change

    def __connect(self):
        self.__conn = smtplib.SMTP()
        self.__conn.connect(mm_cfg.SMTPHOST, mm_cfg.SMTPPORT)
        self.__numsessions = mm_cfg.SMTP_MAX_SESSIONS_PER_CONNECTION


    def __connect(self):
        self.__conn = smtplib.SMTP()
        syslog('smtp-failure', 'host = %s, port = %s',
               mm_cfg.SMTPHOST, mm_cfg.SMTPPORT)
        x = self.__conn.connect(mm_cfg.SMTPHOST, mm_cfg.SMTPPORT)
        syslog('smtp-failure', 'connect returns: %s', x)
        self.__numsessions = mm_cfg.SMTP_MAX_SESSIONS_PER_CONNECTION
