I think IP and other things is this log is not a security hole :-) Tomorrow I think I will see the problem, when a lot of messages will be fetched. The problem is that my sendmail is not failing to deliver, but only is waiting (maybe for DNS Query). I seen that if I send the same messages 100 times, the system is querying dns for the same MX 100 times. tnx.. see you tomorrow Ambrogio
