That is the file i patched SMTPDirect.py

 57 class Connection:
     58     def __init__(self):
     59         self.__conn = None
     60
     61     def __connect(self):
     62         self.__conn = smtplib.SMTP()
     63         self.__conn.set_debuglevel(1)
     64         self.__conn.connect(mm_cfg.SMTPHOST, mm_cfg.SMTPPORT)
     65         self.__numsessions=mm_cfg.SMTP_MAX_SESSIONS_PER_CONNECTION

So after playing with it for a while...I figured the exception is here...

  381     except (socket.error, IOError, smtplib.SMTPException), e:
    382         # MTA not responding, or other socket problems, or any
other kind of
    383         # SMTPException.  In that case, nothing got delivered,
so treat this
    384         # as a temporary failure.
    385         syslog('smtp-failure', 'Low level smtp error: %s,
msgid: %s', e, msgid)
    386         error = str(e)
    387         for r in recips:
    388             refused[r] = (-1, error)

Is there a way to manually get the debug info from smtplib
(conversation with postfix) within this file? debuglevel works if i do
it by hand...

I could add something like this, its just where?
syslog('smtp-failure', 'conversation with smtplib: %s', e)

Also,
the emails seem to go through. Then they stop and then go after i do reopen.
