core-8.6.80.621: German Umlauts broken in the subject line of sent mails

noise

@zara-kopa i’m running at nginx and also in fpm and still have the problem…
it is possible that comes from mysql (mariabd)
The Kollation of kopano innodb is: utf8mb4_general_ci ?

Hi guys

i come back to my old problem because i think its solved with the latest update (i not update since may 2019) and i leave the umlauts problems…

so i update all including system to 18.04.3 LTS
(over 200updates) and kopano to 8.7.82.92

after this update spooler & dagent stops working with transport, so i deactivate the plugIns. now the umlauts problem are gone with nginx.

Perhaps it was the option “plugin_enabled = yes” in dagent or spooler. i don’t know but it works now.

I think the main factor was probably https://forum.kopano.io/topic/2536/webapp-3-5-7-final-available

Can you give some more details as to the “stops working with transport”?

i delete my last logs about this but i make some notices for myself…

the services are all running after the update, but send and receive a mail was not possible.

here are my workaround of this, but here are the wrong topic about this ;-)

First logs:

==> /var/log/mail.log <==
Sep  1 16:00:46 smtp kopano-dagent[16540]: Python traceback is on stderr (possibly check journalctl instead of logfile)
Sep  1 16:00:46 smtp kopano-dagent[15161]: Python threw an exception:
Sep  1 16:00:46 smtp kopano-dagent[16540]: K-1731: Unable to initialize the dagent plugin manager: Unknown error code (1).
Sep  1 16:00:46 smtp kopano-dagent[16540]: < 503 5.1.1 Internal error during delivery
Sep  1 16:00:46 smtp kopano-dagent[16540]: > QUIT
Sep  1 16:00:46 smtp kopano-dagent[16540]: < 221 2.0.0 Bye
Sep  1 16:00:46 smtp kopano-dagent[16540]: LMTP thread exiting

so i found something about the permissions in
/var/run/kopano/server.sock
/var/run/kopano/prio.sock

But the rights are corectly, i change only

ls -la /var/run/kopano/gateway.pid
-rw-r--r--  1 root   kopano    5 Sep  1 17:17 gateway.pid
to
chown kopano:kopano /var/run/kopano/gateway.pid
-rw-r--r-- 1 kopano kopano 5 Sep  1 17:17 /var/run/kopano/gateway.pid

2nd logs are:

Sun Sep  1 18:11:31 2019: [error  ] Use of Python (plugin_enabled=yes) forces process_model=fork
Sep  1 18:11:24 smtp slapd[1538]: <= bdb_substring_candidates: (cn) not indexed
Sep  1 18:11:31 smtp kopano-spooler[803]: Python threw an exception:

==> /var/log/kopano/spooler.log <==
Sun Sep  1 18:11:31 2019: [crit   ] [ 5966] K-1733: Unable to initialize the spooler plugin system: Unknown error code (1).

so i disable plugins to “no” and uncomment directories in spooler & dagent and it works.

Hi all

i come back again here… 🙈
i had a lots problem with mapi and search that i now solved, then i upgrade to the latest version. Kaldav i have not installed allreday.

But my umlauts problem has reversed now, webapp and imap (gateway) seems to be ok, but now z-push makes not a right conversion.
i have also updates z-push

Z-Push:   2.5.1+0-0 
PHP-MAPI: 8.7.82

The umlauts fail is only at the subject, inside the message there is no problem.

Edit:

i delete the device from z-push and do a completly resync,
by a iPhone and android 9 this not resolve the problem on the iPhnoe, but on the android already.
so i delete the account from iphone and the delete a second time the devices from z push.
Now it seems to be ok, but not shure how long :-)

noise

Report:
the umlauts problem still persists with z-push and also in contacts.
at the webapp is solved, there i don’t saw anymore.

Hi together,
my solution to remove the umlauts problem after the kopano upgrade to the current version was to change the webapp PHP default fallback language to “en_US.UTF-8”. I have done this in the file “/etc/kopano/webapp/config.php”:

        //      define('LANG', 'en_GB'); // default fallback language
                define('LANG', 'en_US.UTF-8'); // default fallback language

So commented the old value “en_GB” and using the new one “en_US.UTF-8”.
After reloading the webapp in the browser all umlauts are there again.

Before I have changed the “config.php” I also changed the charsets in the following files to UTF-8. This did not help for the webapp, but I hope it will prevent other charset problems in future.

spooler.cfg:#charset_upgrade = windows-1252
spooler.cfg:charset_upgrade = utf-8

unix.cfg:# fullname_charset = iso-8859-15
unix.cfg:fullname_charset = utf-8

IIIMIIIRIII

My solution:

Changed the configuration of apache2 in:
/etc/apache2/envvars

changes:
“export LANG=C”

to

“export LANG=de_DE.UTF-8”

service apache2 restart

restart the apache server and then it works.

I have now been hit by this problem as well. In summary:

Subject lines for emails show ? instead of Umlaut
E-Mail body and folder names are unaffected
Contact names display ? or multiples of ?? in Webapp but work via Z-Push as well as external email clients (evolution)

My setup:

CentOS 7 & 8
Nginx

Fixes I tried as referred to in other of the many threads on the issue:

set KOPANO_LOCALE and KOPANO_USERSCRIPT_LOCALE to de_DE.utf8 in /etc/sysconfig/kopano
set default fallback language for webapp to en_US.UTF-8
apache envvars do not apply as I am not running apache at all

Webapp:

Evolution:

Changing the name of the contact via Z-Push or Evolution changes nothing about the display in Webapp.
Changing the name in Webapp converts the name to “Dhn” upon saving, dropping the Umlaut alltogether.

Kopano Webapp is the only application hosted on my server that displays these issues, everything else works fine.
It’s alarming how nothing is done to address these issues which clearly affect so many people.

What has been done to address this issue was a fix in webapp back in september: https://forum.kopano.io/topic/2536/webapp-3-5-7-final-available

If that did not fix your issue I would recommend to reach out to our support so someone can check what is different on your system.

This topic is about a mixture of different effects and its doubtful they have all the same source and solution, therefore I am locking this topic now. If you see something similar on your system please reach out to our support, if you don’t have a subscription please at least include version and system information/configuration in your new topic.

PS: and of course the last working version if you had one.
