Notice helo equals '37.212.64.248' - an address literal.
Please READ the RFC. That form is INVALID.
I think you are referring to the square brackets - I knew about them. I
didn't pick up the logic in the system message. Sorry.
Never the less, '37.212.64.248' is not a domain name, so

What the documentation says is incorrect. Under '3.6 Domains' of RFC
2821, it says a host name can be an address literal. So, if I use

Hello,
I have an issue with spam. To tackle the issue, I am going configure my
Postfix-based SMTP server by enabling 'reject_non_fqdn_helo_host name',
which will reject mail from clients that are not using a FQDN as their
host name (such as 'localhost').
