See section 4.1.3 and 4.1.2 - address literals must be enclosed in (square) brackets:
[...Section 4.1.2...]
address-literal = "[" IPv4-address-literal /
IPv6-address-literal /
General-address-literal "]"
; See section 4.1.3
[...]
i.e. from my reading of this:
HELO 1.2.3.4
is not legal, whereas
HELO [1.2.3.4]
would be.
