Please change this to:
Code:

smtpd_milters = , inet:127.0.0.1:12768, inet:127.0.0.1:8891

Please restart the services postfix, dovecot, opendkim and pc-remote after your changes:
service postfix restart && service dovecot restart && /etc/init.d/opendkim restart && /etc/init.d/pc-remote restart​

Second, please make sure, that you set the DNS - entries not only over your Plesk Control Panel, but as well on your primary nameserver ( mostly the one from your domain - provider, where you purchased the domain! ).
 
Thanks you for your replay
i didt this and the problem with internal messege is now solved ! thanks
but other problemes are not
when i become an email from outside the server i didnt get it and this is again the maillog

when i test another domains from my server i got that they have dkim valid signuar but my main domin not more :(

and what else when i test for example [email protected] and [email protected] i got 2 different resullt !! but they are in the same domain .. the dkim ok is valid but for example the
DMARC is not

sorry that i sent more than problem but maby they have the same solution ..

thanks in advance

Please make sure that opendkim is started and is listening on port 8891 ( check as well your configuration files, please! ).

netstat -nlp | grep :8891
​
If opendkim is not started, then you will always see the described errors in your logs.

Sorry, but without the correct domain - name, suggestions will be pretty undefined. We can't check what might be wrong.

Click to expand...

Again... without your correct domain-name, we can only guess.... which is pretty time-investing. If you have a missing DMARC - entry in your DNS, there will always be a false positiv for it.

Example entry:
Code: 
    _dmarc.YOUR-DOMAIN.COM.    TXT    v=DMARC1; p=none

Hello UFHH01 ;)
Thanks for ur replay

i dont know where is the problem when i tried to enter netstat -nlp | grep :8891
so i got nothing but after restart opendkim service first time i got error but second time it could be succssefully restarted and then i get those
[root@server ~]# netstat -nlp | grep :8891
tcp 0 0 127.0.0.1:8891 0.0.0.0:* LISTEN 16561/opendkim

my domain name is palstudenten.com
dkim sector is mail
i added all those dkim and dmarc etc ..
 
Hi Szer0P,

first, your server is vulnerable. Please see: https://www.ssllabs.com/ssltest/analyze.html?d=palstudenten.com

To start, you might consider to secure your server with the help of the thread: SSL POODLE / SSLv3 bug ( Forum thread link )


Second, please consider to adjust your SPF - entry:

Code: 
v=spf1 a mx ptr a:server.palstudenten.com mx:palstudenten.com ip4:79.143.179.239 ~all

Code: 
"mx:palstudenten.com"
is a double entry, because "v=spf1 a mx" already contains all "A" and "MX" entries, that you set on your nameserver.


As well, you could consider adding the DNS - entry:
_adsp._domainkey.example.com. TXT dkim=unknown
or
_adsp._domainkey.example.com. TXT dkim=all
Click to expand...
"unknown" defines, that some mails are signed - some may not..... and "all" defines, that all mails from the domain will be signed.


Consider adding valid PTR records ( if available at your provider ) so that reverse checks fit you mail-server-settings:
79.143.179.239 / 24 PTR palstudenten.com.
79.143.179.239 / 24 PTR server.palstudenten.com.
79.143.179.239 / 24 PTR mail.palstudenten.com.
Click to expand...

Third, your DMARC - entry is quite strict and may result in eMail - rejections, if any of your settings fail or softfail. Consider using the suggestion above, please.

Fourth is the recommendation not to use sendmail, when using PHP - forms, because it's a bit tricky, to tell sendmail how it should sign mails with DKIM and/or OpemDKIM. A rather easy solution is to use a contact form with SMTP - login over a dummy eMail - adress like "[email protected]". If you still insist in using sendmail, please google for solutions/suggestions/tutorials.


If you still experience issues, please add eMail - headers from the specific eMails and include as well depending log - entries from your mail.log for further investigations.

after Resoterd the Backup the configuration still having problems

Hi Szer0P,

first of all..... please get yourself a cup of coffee/tea, or what ever may relax yourself a bit.... there is nothing, which can't be reversed.


as you can see in the error log... you have TWO values with "TLSv1.1" and "ssl_ciphers" in your configuration files. but the statement "server.conf" is a bit confusing.... because this will be the mostly not directly in the server.conf, but in the depending *.conf files, located at: "/etc/nginx/conf.d/*".... and unfortunately, this will be the file "zz010_psa_nginx.conf", which contains more links, to the other folders at:

/etc/nginx/plesk.conf.d/webmail.conf;
/etc/nginx/plesk.conf.d/vhosts/*.conf;

But now, please keep in mind, WHAT you changed. If you followed the suggestions in the thread, you changed "nginxWebmailPartial.php" "server/nginxVhosts.php" "domain/nginxDomainVirtualHost.php"

- so please go to that folder and have a look at the *.conf - files there, and try to find double entries in the depending domain files at: "/etc/nginx/plesk.conf.d/vhosts/" and "/etc/nginx/plesk.conf.d/webmail.conf"

... another hint for it : The folder "/etc/nginx/plesk.conf.d/vhosts/" contain symlinks to the domain - config files located as for example at:

/var/www/vhosts/system/example.com/conf/nginx.conf
/var/www/vhosts/system/example.com/conf/httpd.conf​

and either post the depending entries, so others may tell you, what will be correct, or do it on your own, having another look at the single posting:

You might have missed to create the new certificate:

Move to the folder: /etc/nginx/
Code: 
openssl dhparam -out dhparam.pem 4096
Be aware, that this may take a while to finish!

Afterwards, the correct entries in the nginx - templates ( "nginxWebmailPartial.php" "server/nginxVhosts.php" "domain/nginxDomainVirtualHost.php" , would be:
Code: 
ssl_session_timeout         5m;
ssl_session_cache shared:SSL:50m;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA+RC4 EECDH EDH+aRSA RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS";
ssl_prefer_server_ciphers on;
ssl_dhparam /etc/nginx/dhparam.pem;

Please be sure, to modify the templates in a "custom" directory ( "/opt/psa/admin/conf/templates/custom/" ) , to be sure, that Plesk doesn't touch your modifications.

Thanks also can anyone answer me ;)

i made this last night .. but after the problem i deleted this file /usr/local/psa/admin/conf/templates/custom/ and now i made this changes again as it above mentioned

all the three document i changed it to>
Code: 
<?php if ($OPT['ssl']): ?>
<?php $sslCertificate = $ipAddress->sslCertificate; ?>
<?php   if ($sslCertificate->ce): ?>
    ssl_certificate             <?php echo $sslCertificate->ceFilePath ?>;
    ssl_certificate_key         <?php echo $sslCertificate->ceFilePath ?>;
<?php       if ($sslCertificate->ca): ?>
    ssl_client_certificate      <?php echo $sslCertificate->caFilePath ?>;
<?php       endif ?>
    ssl_session_timeout         5m;
    ssl_session_cache shared:SSL:50m;
<?php if (get_param('disablesslv3')): ?>
    ssl_protocols               TLSv1 TLSv1.1 TLSv1.2;
<?php else: ?>
    ssl_protocols               SSLv2 SSLv3 TLSv1 TLSv1.1 TLSv1.2;

    ssl_prefer_server_ciphers   on;
    ssl_dhparam /etc/nginx/dhparam.pem;

Double entry...., please take the "ssl_protocols TLSv1 TLSv1.1 TLSv1.2; " ....but I'm not sure, that you investigated all configuration files, because it states, that there should be as well another double entry for "ssl_ciphers ..." .

Please see again this post:

http://talk.plesk.com/threads/ssl-poodle-sslv3-bug.323338/#post-761018

It states quite clear step-by-step how and what you should do, if you secure your server.
 
Hello UFHH01

I did step my step the tech01 on the other post and i found this file as u see above and all the three files are the same .. should i now delete from the three files in
/usr/local/psa/admin/conf/templates/custom/

the line ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ?

in the
/usr/local/psa/admin/conf/templates/default/nginxWebmailPartial.php



Code: 
<?php if ($OPT['ssl']): ?>
<?php $sslCertificate = $ipAddress->sslCertificate; ?>
<?php   if ($sslCertificate->ce): ?>
    ssl_certificate             <?php echo $sslCertificate->ceFilePath ?>;
    ssl_certificate_key         <?php echo $sslCertificate->ceFilePath ?>;
<?php       if ($sslCertificate->ca): ?>
    ssl_client_certificate      <?php echo $sslCertificate->caFilePath ?>;
<?php       endif ?>
    ssl_session_timeout         5m;

<?php if (get_param('disablesslv3')): ?>
    ssl_protocols               TLSv1 TLSv1.1 TLSv1.2;
<?php else: ?>
    ssl_protocols               SSLv2 SSLv3 TLSv1 TLSv1.1 TLSv1.2;
<?php endif ?>
    ssl_ciphers                 HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers   on;
<?php   endif ?>
<?php endif ?>

i see this .. that what i copied to this file /usr/local/psa/admin/conf/templates/custom/ and there is only double entry for the ssl_protocols .. i saw the other postes and i saw a soultion for the double entry for the ssl_protocols but it has nothings changed
u can see here

Code: 
[root@server ~]# mysql -uadmin -p`cat /etc/psa/.psa.shadow` -Dpsa -e "insert into misc values('disablesslv3', 'true')"
ERROR 1062 (23000) at line 1: Duplicate entry 'disablesslv3' for key 'PRIMARY'
[root@server ~]# /usr/local/psa/admin/bin/httpdmng --reconfigure-all
[root@server ~]# cat /var/www/vhosts/system/*/conf/last_nginx.conf | grep ssl_protocols
    ssl_protocols               TLSv1 TLSv1.1 TLSv1.2;
    ssl_protocols               TLSv1 TLSv1.1 TLSv1.2;

i dont know what should i do now to fix this problem ?
thanks
 
Hi Szer0P,

once again.... you have TWO TIMES an entry for "ssl_protocols ...", which doesn't work! Please delete the additional second entry from the template(s) AND from the configuration file!
 
Hello UFHH01,

Sorry for asking too much, im really sorry for that ..

the thre files
/usr/local/psa/admin/conf/templates/custom/
/usr/local/psa/admin/conf/templates/custom/server/
/usr/local/psa/admin/conf/templates/custom/domain/

i deleted the additional second entry to ;

Code: 
<?php if ($OPT['ssl']): ?>
<?php $sslCertificate = $ipAddress->sslCertificate; ?>
<?php   if ($sslCertificate->ce): ?>
    ssl_certificate             <?php echo $sslCertificate->ceFilePath ?>;
    ssl_certificate_key         <?php echo $sslCertificate->ceFilePath ?>;
<?php       if ($sslCertificate->ca): ?>
    ssl_client_certificate      <?php echo $sslCertificate->caFilePath ?>;
<?php       endif ?>
    ssl_session_timeout         5m;
    ssl_session_cache shared:SSL:50m;
<?php if (get_param('disablesslv3')): ?>
    ssl_protocols               TLSv1 TLSv1.1 TLSv1.2;
<?php else: ?>

<?php endif ?>
    ssl_ciphers "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+$
    ssl_prefer_server_ciphers   on;

Is this right ? im sorry agian
i read that u said that we have not to edit the default files .. so i changend only in the custom files ..
 
Hi Szer0P,

well, if your "default" files contain as well double entries, they are not flying into the configuration... there must be a tiny little man, who put it there. Please check as well the default files. :)

YES! This is just what I was suggesting. :)


After all, when you are sure, that you deleted the double entries ( again, not only in the template - folders, but as well in the current configuration files! ), please regenerate once again all your webserver configuration files with the command:

/usr/local/psa/admin/bin/httpdmng --reconfigure-all
​
and smile afterwards, because now all should work as expected!

Good :)

but what do u mean with not only in the template - folders, but as well in the current configuration files! ?

sorry but i want to be sure that i changed all of this

/usr/local/psa/admin/conf/templates/custom/
/usr/local/psa/admin/conf/templates/custom/server/
/usr/local/psa/admin/conf/templates/custom/domain/
"nginxWebmailPartial.php" "server/nginxVhosts.php" "domain/nginxDomainVirtualHost.php"
I have changed the Three files, this is what do u mean with configuration files ?

when i did all corectily .. so can we return to the dkim email problems ?
 
Hi Szer0P,

please consider reading some basic informations about log - files and depending configuration files:

so i think i solved the problem :)

thanks alot ;)

can u please tell me how to fix the dkim problem now ?

have a nice day
 
Hi Szer0P,

in your previous post you already got the milter working again. As far that I inverstigated, you should only change your strict settings, in order to get DKIM to work. Please report again with ACTUAL log - error - entries to investigate any problems.
 
i still having problem with the opendkim !
see the error log i see this for more than 100 times i musst everytime to restart the dkim to solve this problem ..
Code:

and another problem when i send an email to my server from hotmail for example i get this error

smtpd_milters = , inet:127.0.0.1:12768, inet:127.0.0.1:8891
#non_smtpd_milters = $smtpd_milters

the dns setting for my domain is:
