Thank you. I will re-visit this next after the proxy problem is solved.
Btw, thank you very much for suggesting HAProxy's proxy protocol. I've
succeeded in getting it partially to work (I'm not done yet, there's
more to configure), and I can see external IP addresses in postfix and
dovecot
In my case, I reject invalid HELO names with:
reject_invalid_helo_hostname
reject_non_fqdn_helo_hostname
I've run postfix like this for about 10 years now without any problems. I don't
expect others to use such restrictions but it works for me.

I see. Thank you for the explanation. So the right way to state this is
that HELO/EHLO requires a valid FQDN/hostname only for MTAs, and for
MUAs it's just ignored because authentication is what matters.
Cheers,
Sam

It still needs to be sent for submission connections, but the hostname
does not have to be a legitimate FQDN. What is important for submission
is that it passes some

Thank you very much, Raf. I really appreciate your empathy and all this
help.
I'm reading more and more every day. I really appreciate your support.
The challenge is knowing what matters.
And about your HELO definition, thanks for explaining it. What confuses
me is that clients usually
Dear Matthias,
I think there's a misunderstanding here. The server is already shutdown.
I thought you meant that I should shutdown the server permanently and
move on with my life because I'm incapable of running a server, which

It's good that you're willing to learn, but perhaps you can do some
experiments on a "internal" environment before exposing it to the
full internet.

Hello,
when I receive "Delayed Mail" notification, the message only has the
header of the original email.
Is it possible to have the full email body included in the notification
message, so that I can see which email has not been delivered?
I am dealing with a remote mail server, which uses
