True, good news J
I install centos + toaster on several comp several time in last month
and test in many ways. Without effect. Yesterday I try centos 6 and
nothing change. JBut finally I have new knowledge. J
For now. I create test account on outlook.com And test itself. When I
delete from named.conf:
server ::/0 {
edns no;
};
server 0.0.0.0/0 {
edns no;
};
I can’t receive email from outlook.com. When I add it back every.
Works fine. :)
Many thanks,
Marek
Ps.Tomorrow I write post to qmailtoaster list with solutions. Maybe we
save time someone.

I've been worried about this for a month or so, or since you brought
it up the first time.
This is truly good news.

Yes! That could also be an issue. That's what I meant yesterday
when I said, "It could be something in between you and you
client." Something like a firewall, router, dns server, etc...
Hopefully we've resolved this issue.

Unfortunately now Is to late, and I can’t get test message
from my client from Dupont. I check it tomorrow.
I found this:
https://ubuntuforums.org/showthread.php?t=1368976 what do you
thing about it? Posible is EDNS is a reason? Why I notice only
dupont domaintimeout?

You must change the DNS setting for your interface or
/etc/resolv.conf will revert back to 37.235.1.174 on restart.
# yum install NetworkManager-tui
# nmtui (change DNS for interface to 127.0.0.1 )

Yes. I use bind (systemctl start/enable named) with
127.0.0.1 in /etc/resolv.conf.
What's in /etc/resolv.conf?
I'd try something different.

Have a look at this thread on the Postfix user's
mailing list concerning mail coming from
protection.outlook.com :

This site also indicated that your server was
capable of strong tls encryption
https://luxsci.com/extranet/tlschecker.html
(Strong TLS is supported by the inbound email
servers for demod.pl.)

I was looking at the Undeliverable email your
client sent me particularly the following line:
"11/27/2016 7:54:24 PM - Server at
mail.demod.pl (25.152.64.27) returned '451
4.4.398 Error communicating with frontend
host. -> 421 4.4.2 Connection dropped due to
ConnectionReset'"
The address associated with mail.demod.pl,
25.152.64.27, in the above error is NOT the IP
of your mail server. Can you explain? Is there
a DNS setting that needs to be corrected?

I'm not sure what to say. The only
difference between your CentOS 7 setup and
mine is that I'm not running SPAMDYKE on
it. I am receiving email on the CentOS 7
setup albeit ~5 minutes after the initial
connection. This may have to do with the
Sonicwall I have in front of my mail
server that acts as a proxy. Let me do
some investigation and I'll get back to
you. I will be in contact with your client
to perform tests if that's okay with you
and him.

Do the following:

Have dupont send a test email and

My home mail server is a

The other a CentOS 7 qmt
both received every email
although with the CentOS 7
server there is an initial
connection then I receive the
email 4 to 5 minutes later.
I'll have to look into it.
