Re: [qmailtoaster] Qmail reject email from several domain Reason TIMEOUT

[Eric Broch]

Marek,

OK, It seems that the older version of this patch 
(netqmail-1.06-tls-20160918.patch) is already implemented on the current 
Qmailtoaster package, but I'm not sure how to implement it or how to 
stop SPAMDYKE from blocking it.

This is the version used now:

http://inoa.net/qmail-tls/netqmail-1.05-tls-20060104.patch

The claim in the qmailtoaster patch (qmailtoaster-1.3.2.patch), below, 
is that it has been used successfully since 1999.

"This patch implements RFC 3207 (was RFC 2487) in qmail.
This means you can get SSL or TLS encrypted and
authenticated SMTP between the MTAs and from MUA to MTA.
The code is considered experimental (but has worked for
many since its first release on 1999-03-21)."

If anyone has any information on this please chime in.

Thanks

Eric

I think this (http://inoa.net/qmail-tls/) is the patch you're looking 
for. I'll check into it when I have a little time.

Explanation of the patch @ http://www.memoryhole.net/qmail/#starttls :

SSL (STARTTLS)
    SMTP transmits email unencrypted. Other than privacy concerns,
    this is not typically a problem. However, if you use SMTP AUTH,
    you are sending your username and password across the network in
    plain text (which is easy for a hacker or spammer to extract if
    they wanted to). The solution is to use encryption in SMTP — in
    other words, make qmail support the STARTTLS ESMTP extension.
    Frederik Vermeulen wrote a patch to get it to work. It adds one
    minor step to the compilation of qmail: you must create a server
    certificate (run |make cert| before running |make setup check|).
    Also, you must create a cron job to rebuild the certs daily
    (because otherwise, over time, an attacker could figure out what
    they are). Commonly, when someone indicates that they want qmail
    to support SSL/STARTTLS they will be referred to a project like
    mailfront <http://untroubled.org/mailfront/>. While mailfront is a
    worthy project, it doesn't always solve the entire problem.
    Specifically, it doesn't enable qmail to use SSL for /sending/
    mail to other servers that support STARTTLS (this is a problem of
    privacy; but keep in mind that if the email is being relayed, it
    may be transmitted via an unencrypted communication later---if
    you're really worried, use PGP). This patch, however, does enable
    qmail to do that. (local copy

After further review are you looking for Secure Inbound Email (SMTP TLS)?

Again, I ask, is there a reason that they(104.47.42.63) are using 
TLS to connect to port 25 and transfer email to your server 
(192.168.0.25) ????  : See "encryption: TLS" in your log (below).

Again, why are they using TLS to connect to your server over port 25 
for standard email transfer???

This is the problem and the reason for the error!

Someone correct me if I'm missing something.

If they (104.47.42.63) know the username and password of the 
recipient on your server (192.168.0.95) you can use 
authentication--qmail allows for this, but why would you do it that 
way? This is only for internal--your network--forwarding of messages 
to another server. You would not do it this way unless you were 
willing to give them individual account information and they were 
willing to set up rules. They would then forward to port 587.

Hi,

This is my recordio log  for rejecting session. Where is the problem?

Isthere any way to configure my server to allow this mail?

        It looks like the email is going to no one, you could check
        in the send log at the same time, but I doubt any delivery
        is being made. It might be being rejected at 'policy.' It
        should be followed up with delivery. Below is what a
        complete smtp transaction looks like:

            From your first email you stated that, "This occurs
            only on several big corporate domain like dhl.com
            man.eu ergohestia.pl"

            Obviously you are receiving at least some mail,
            correct? So, whatever the cause of this problem,
            spamdyke or otherwise, barring the corporate domains,
            in many cases your email server is working correctly,
            right?

            Maybe the other server ARE actually taking more time
            than they should. This is all that I was saying.

            Can you remove spamdyke from the 'run' script as I
            suggested and give that a try?

                What I meant was this: could it be that spamdyke is
                actually doing what it is supposed to do. Is
                spamdyke timing out a connection when it takes to
                long and allowing connections when the connection
                is within the time limit?

                In other words, how do you know its not working
                properly?

                        If this doesn't work, can you refert to
                        spamdyke 4 and let us know if that works?

                            I expand to:

                            It looks to me like it's spamdyke
                            causing the problem. It's certainly
                            what the log suggests. What is your
                            'idle-timeout' setting in
                            /etc/spamdyke/spamdyke.conf

                                Hi,

                                From some time i have a problem
                                with my qmail server. From some
                                time the server reject mail from
                                several domain REASON TIMEOUT. I
                                don’t know why. This occurs only on
                                several big corporate domain like
                                dhl.com man.eu ergohestia.pl. First
                                i suspect spamdyke. But i check it.
                                Enter white list etc. Ask on
                                spamdyke forum and final look at
                                the spamdyke don’t block anything.

                                The excessive log file show only:
