In RFC 1035, I am curious about section 3.3.6, which reads:
3.3.6. MG RDATA format (EXPERIMENTAL)
/ MGMNAME /
MGMNAME A <domain-name> which specifies a mailbox which is a member of the mail group specified by the domain name.
MG records cause no additional section processing.
QUESTION: I'm trying to understand how this all works -- it seems the domain name specifies a mailbox that's specified by the domain name. Can someone explain this better?
