What are your DNS servers?

Marek,

This is good!!! I tested with bind without edns settings, localhost as name server, and it took 2 tries for outlook.com but ultimately delivered email. Since it does not deliver on your system without the edns settings I'm wondering if there is not something else going on as well with DNS servers in your area...as long as it works now, though...whew!

Also, I installed djbdns-localcache and removed bind, localhost as nameserver, and the mail delivered 1st time. I'll test PowerDNS tomorrow.

Glad everything is working and I don't have to delve into Qmail-TLS.

As an aside, I've been looking into the most recent qmail AUTH and qmail tls patches for qmailtoaster here <http://www.fehcom.de/qmail/smtpauth.html> and here. <http://inoa.net/qmail-tls/>

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.

Wow!!!!

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.

        Yes, You right. I change it.

        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.

                Sounds similarly. But i use a  Bind and I no idea how
                to fix it :( Could be a DNS reason maybe I should try
                different dns server?

                Have a look at this thread on the Postfix user's

                    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.)

                        Maybe the mail is sent at the moment  when
                        the server is not configured completely?

                                    Marek,

                                    Do the following:

                                    # cd /var/qmail/control

                                    # cp -p tlsserverciphers
                                    tlsserverciphers.bak

                                    # openssl ciphers > tlsserverciphers

                                    # qmailctl stop

                                    # qmailctl start

                                    Have dupont send a test email and
                                    let me know what happens.

                                        My home mail server is a
                                        CentOS 6 qmt

                                        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.
