i cannot send out to some domains when im opening the message details in queue viewer in my exchange 2010 i can see the error
Last Error: 450 Client host rejected: cannot find your hostname, [xxx.xxx.xxx.xxx]
the internal mail server name is different than the DNS record i configured in NetworkSolution
on network solution is mail.domain.com
and in the actual server name is servername.domain.com
i configured my internal DNS to have MX record for mail.domain.com and it points to ip of servername.domain.com
to save your time i connected to PC out of the network and with different ISP and i run the following
is the problem because of the revers ?????????
