In 4.1.1.1 it says (this is new material which was not in 821):
In situations in which the
SMTP client system does not have a meaningful domain name (e.g., when
its address is dynamically allocated and no reverse mapping record is
available), the client SHOULD send an address literal (see section
4.1.3), optionally followed by information that will help to identify
the client system.
However reading the syntax carefully, I can see no specification for the
optional information. The ABNF specifies just a domain or an address
literal :-(
ISTR that there was discussion at one time about allowing optional
free-form text after <Domain>, but this idea was shot down. I think the
text you're referring to might be there due to an editing error. If you
look at the top paragraph on page 30 of RFC 2821, the second sentence has
a stray " y " at its head, leading me to believe we might have a simple
snarf-and-barf error here.
John, can you comment on this?
