Hello,
If I use the 'smtpd_helo_restrictions' option parameter
'reject_unknown_helo_hostname', will a hostname that is an address
literal be rejected?

in form, as required by the RFC."
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
'reject_non_fqdn_helo_host name' and a SMTP client uses an address
literal for its host name, will Postfix reject the mail?

Hello,
Postfix has a bug in it where argument 'reject_non_fqdn_helo_hostname'
causes Postfix to reject mail from a client who is using an address
literal as their 'helo' command.
This in breach of RFC 2821 under section 4.1.1.1.

Of course not.
According to my mail

Your claim is valid. Address literals in HELO must be enclosed in [].
I am a little confused. Were you just correcting me
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
'reject_
e-mail server
enforcing 'reject_non_fqdn_helo_hostname' accept my mail, or would the
PTR record have to resolve to '123.243.137.139' exactly (not
'123-243-137-138.static.tpgi.com.au')?
There is allot I don't know about DNS. Does anyone know if a PTR record
can be set to resolve to an IP address?

From what I understand, 'reject_non_fqdn_helo_hostname' and
'reject_invalid_helo_hostname' detect malformed 'helo', but
'reject_non_fqdn_helo_hostname' does not detect malformed 'helo' if
'helo' is a malformed address literal.

The way I see it is if there is no FQDN and the host name is invalid,
then 'reject_unknown_helo_hostname' won't be able to verify the DNS A
