Is it possibe to get this to work ore do i need to get me another domain for the ISPC v3 server aka s10.mydomain.se? "I got no problem to send mail from mail.mydomain.se" to s10.mydomain.se Regards Marcus
Solved Hi, Solved this problem by change DNS servers from internal DNS servers that host mydomain.se to my External DNS servers that points to FW on the outside interfaces. Regards Marcus
