So, based on this latter paragraph, it is entirely OK to reject
after "EHLO 127.0.0.1", since that is not a properly formatted EHLO
argument. RFC821 has similar restrictions on the HELO argument,
which should be a "domain" (no IP allowed).
RFC821 is funny, because it allows this:
[1.2.3.4].[1.2.3.6].#123445.DummDiDumm
relevant EBNF:
<domain> ::= <element> | <element> "." <domain>
<element> ::= <name> | "#" <number> | "[" <dotnum> "]"
<dotnum> ::= <snum> "." <snum> "." <snum> "." <snum>
<number> ::= <d> | <d> <number>
<snum> ::= one, two, or three digits representing a decimal
integer value in the range 0 through 255
EHLO's argument is defined more restrictive.
BTW: That somebody knows what the "#" <number> element is used for?
