question regarding RFC 1035

In RFC 1035, I am curious about section 3.3.6, which reads:

3.3.6. MG RDATA format (EXPERIMENTAL)
+
/                                                                                                       /
/                                         MGMNAME                                               /
/                                                                                                       /

where:
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?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Here's how I understand it:
1. There's a mailbox that is a member of a domain.
2. There's a mail group that is a member of the same domain.
3. The mailbox (1) is a member of the mail group (2).
4. MGMNAME is a domain name that specifies the mailbox (1).  [Not sure at all on this one.]

I'm guessing then that MGMNAME stands for "Mail Group Member Name."  Beyond that, though, I'm afraid I can't be too much help without reading the whole RFC.

Not necessarily abandoned; just hoping for an easier to understand answer.

Sarah,

If you needed an easier-to-understand answer, all you had to do is ask.  Is there any particular part that you're still unsure about?

Sorry. I am really just trying to understand how MGMNAME is used and what it's used for. The definition it comes with is too confusing for me.

You know, I could keep trying to guess, but they would be just that - guesses.  It may be best just to delete this question and start over.

LearnedOne - I propose a "delete with refund" so SarahMoore can ask this question again.
