This is one of the actual rebounce report ( I tried sending from several
machines/senders/places ), from the system administrator :

( 222.124.xxx.xxx is off-LAN address )

In a rebounce report. In other reports, it mentioned other IP address if I
sent to other name addresses.

I think you are right, but, I can't prove. Pinging to 222.124.57.160, just
didn't resolve the name. All sent, no loss. OK, but, no real name . . .

I didn't conceal, it's just that I forgot ( remember, I was sending the
e-mail from outside machine in other place ).

( this time, I'm sending via my windowz, with SMTP server authentification
checked in outlook )
