Does an A record exist for server.nnn.domain.com.br? If not, how are we supposed to figure out where to actually direct mail for postmas...@nnn.domain.com.br? If you don't have an A record for server.nnn.domain.com.br, I believe you have a dangling MX record. Is the MX record supposed to be ?: nnn IN MX 10 server.domain.com.br. Maybe I've missed something in your problem description. Some very smart people have responded before me without mentioning this. I probably missed something. -- Scott Lambert KC5MLE Unix SysAdmin lamb...@lambertfam.org
