Hi Doug, Hi again, the solution of using an Internal DNS, its very dificult for me, I have about 10,000 customers behind the NAT at my routers, so I will have to disable DNS Lookups in Sendmail, but I cant find how to do it, the only thing I found its this : FEATURE(nodns), in the .mc file, but this didnt worked, I still having the same problem, is this the right feature, or its something I have missed in the sendmail.org Site.
