This might be correct, and the cause might be the fact that I'm conected 
trough ADSL,
which AFAIK gets the local machine name registered at the DNS server (at 
Internet-zahav in my case).
Now i've seen that the mail server back-resolves my IP as 
resof.netvision.net.il.
Have you any idea how do i take the zahav sufix doring the name registration?


And after all I'm (and other more educated spamers) still in a position to 
relay mail trough mailgw...
So I geuss netvision anti-spaming scheme is ill-planed.
