Re: [qmailtoaster] Outlook users get "unsupported encryption type" error after Windows update

[Fabio Mecchia]

Hi, I also
got this problem long ago, I don't remember if this was correct but try to 
add this key to your windows registry :


[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb]
-> Add this key"ProtectionPolicy"=dword:0001

Hi Quinn.

Just think I've seen this looong ago... may be I'm wrong

Check the ports for smtp / pop in outlook - it may relate to the
portnumbers - if it needs to be encrypted try using port smtp 465 / pop 995.
( it requires the ports are in use by the QMT server ofcourse)

Hope this may help

Today we received several complaints from Outlook users who are unable
to connect to QMT servers. They get this error:

Task "u...@example.com  - Sending: reported
error (Ox800CCC1A) :
'Your server does not support the connection encryption type you have
specified. Try changing the encryption method. Contact your mail server
administrator or internet service provider (ISP) for additional
assistance.'

The error began after installing Windows 10 servicing stack update -
19042.1940, 19043.1940, and 19044.1940
, 
and the problem was fixed by uninstalling the update.


Has anyone else experienced this, or know what the problem could be? I
hope there is a config change I can make on QMT servers so that users
will not need to uninstall the update.

Hi,
yesterday morning I've installed the updated dovecot and since then there 
was no problem with the client login.

Problem seems gone .

Thank you all for the great support.

Fabio,
Okay, it's patched.
The new file is dovecot-2.3.11.3-13 in the testing repo with all the 
associated packages. We cannot, from here, go on to 2.3.13 because that 
version no longer supports vpopmail driver.

command will be this:
# yum --enablerepo=qmt-testing update dovecot
I'd wait maybe a day at which time all the qt repos are updated,
or you will find the file on my site at this link: 
http://repo.whitehorsetc.com/7/testing/x86_64/

from which you can download it and install manually.
Eventually, we will all go this route: 
https://www.qmailtoaster.org/manydom.html
and all dnf (yum) settings can be modified so that all rpms will come from 
dovecot.

Hi Eric,
I have already searched the dovecot mailing list and found a few people who
complain about this error exclusively with dovecot version 2.3.11.3
It seems a bug has been introduced on the behavior of the AUTH mechanism.
On the mailing list they recommend patching the sources or upgrading to a
later version.  That's why I was asking how to upgrade.

Re: [qmailtoaster] Weird problem on pop3 connection

[Fabio Mecchia]

In my /etc/dovecot/toaster.conf I Have:
auth_mechanisms = plain login digest-md5 cram-md5

while the /etc/dovecot/conf.d/10-ssl.conf is the same as yours  with :
ssl = required

I've found this on the dovecot mailing list :

[qmailtoaster] Weird problem on pop3 connection

[Fabio Mecchia]

Hi everyone,
 I have been having a weird problem connecting pop 3 to my corporate server
from Outlook and Thunderbird for about two weeks.
When the client tries to connect to the server, I got this error message
"-ERR [AUTH] Unsupported authentication method" and in the Dovecot logs I
found errors like "pop3-login: Info: Disconnected (tried to use unsupported
auth mechanism): user=, method=USER, rip=xxx.xxx.xxx.xxx,
lip=xxx.xxx.xxx.xxx, TLS, session=
" .
The strange thing is that the same client checks multiple boxes on the same
domain and not all of them give an error, also the error occurs randomly,
maybe for half a day it is impossible to download the mail and then
suddenly it works for a couple of hours.
Using the imap protocol there are no problems.
When the clients manage to connect I find this in the Dovecot logs
"pop3-login: Info: Login: user=, method=DIGEST-MD5,
rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, mpid=5510, TLS,
session=<+0htGDnVWPdc3/SS>", I don't know why on the same client without
changing anything the method switch from USER to DIGEST-MD5
The server is up to date, dovecot version is 2.3.11.3


Any suggestions are welcome

Excelent !
Thanks

If you're using spamdyke, put it in /opt/spamdyke/etc/spamdyke.conf

Also you need to sign up with them for the service.

[qmailtoaster] Dkim headache

[Fabio Mecchia]

Hi again,
I'm having a big headache setting up the dkim on my company mail server.
I create a 1024 bit key and set up my dns records also with spf and dmarc.
I've checked it on various test tool:
- mail-tester.com gives me a 10/10 score
- dkimvalidator.com says my signature is valid and pass the test
- the keycheck at dkimcore.org says that my dkim record is valid
- test spf/dkim on mxtoolbox.com give me a valid result

 everything seems perfect 

BUT

- some of our customers are blocking our mail
- on a gmail account reading the headers of my mail  I found "dkim fail
with domain null"
- www.appmaildev.com/it/dkim reports me  "DKIM-Result: fail (bad signature)"
- mail test on en.internet.nl says that "a DKIM record (TXT) could not be
found" but it found the dmarc record (that I set up on dns a day later than
dkim)

Now are more than 36 hours from the last time I've changed a dns records so
I don't think that is a dns propagation problem.
Now I don't know what else I can do to properly setup my server

Thanks in advance
 Fabio Mecchia

[qmailtoaster] Problem with dkim install

[Fabio Mecchia]

Hi all,
I've  done a fresh install of QMT on Centos7, everything went smooth
without any problems.
But I'm blocked on dkim install, I've followed these instructions :
https://github.com/qmtoaster/dkim/blob/master/README.md
but on 7th step "dknewkey /var/qmail/control/dkim/global.key >
/var/qmail/control/dkim/public.txt" I have a command not found error.
For sure I'm missing some step but I can't figure out what it is.

Thank for any help
 Fabio Mecchia
