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
firstname.lastname@example.org? 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.
