Date Sun, 19 Sep 2004 12:18:23 GMT
    Since last wednesday (9/15), james stop sending mails, the smtp is
alive, you can use it, but james does not send the mails in the outgoing
folder (my outgoing folder in the moment has more than 4000 mails..). I
restarted james several times but nothing happened, and I can find no error
