Today, one of our customers at TBits.net noticed that when composing an e-mail in Roundcube, there is a spell checker button at the top. But only for English, and when there was text in the e-mail, and he clicked on the spell check button, he got the message: “An error was encountered on the server. Please try again later.”

I found the cause in the Roundcube log file, in /var/log/roundcubemail/errors:

PHP Error: Spell check engine error: Pspell extension not available in /usr/share/roundcubemail/program/steps/utils/spell.inc on line 50

So I installed the required packages:

yum install php-pspell aspell-de
systemctl restart httpd

Now this works for English. It seems for German and other languages, there are no packages readily available in the repositories.
I checked https://apps.fedoraproject.org/packages/aspell-de, there are packages for Fedora, but not for EPEL.

So you go to https://ftp.gnu.org/gnu/aspell/dict/0index.html#0.60 and download the dictionary for your language, and install it like this on your Kolab server:

tar xjf aspell6-de-20030222-1.tar.bz2
cd aspell6-de-20030222-1
./configure
make
make install

Now do a reload in Roundcube, and now you can check your spelling even in German!

A customer of TBits.net asked about notifications: you set up a filter in Roundcube, and you will be notified whenever an email arrives, and the notification is sent to an email address that you check more regularly. It is not like forwarding the message, but the notification does not contain the message itself, to force you to use Roundcube and keep the contents of the email secure on our mail server. This scenario applies to people working for a company or charity and not checking mails regularly, but wanting to be informed on their private email accounts at GMail or Hotmail or whereever. This way data protection is enforced, but still people know about their new emails.

It took me a while to find this page: https://www.cyrusimap.org/imap/reference/manpages/configs/imapd.conf.html which mentions:

sievenotifier:
Notifyd(8) method to use for “SIEVE” notifications. If not set, “SIEVE” notifications are disabled.

See also https://www.cyrusimap.org/imap/reference/manpages/systemcommands/notifyd.html

So you set in /etc/imapd.conf:

sievenotifier: mailto

And I assume you have in your /etc/cyrus.conf:

notify      cmd="notifyd"   listen="/var/lib/imap/socket/notify"    proto="udp" prefork=1

The notification email will look like this:

Subject: [SIEVE] New mail notification
From:    Mail Sieve Subsystem
Body:
  your customized text defined in the filter
 
  Action(s) taken:

These strings are hard coded unfortunately. I am wondering if I should patch them out in our own build of Cyrus…

Here is the code:

https://github.com/cyrusimap/cyrus-imapd/blob/master/sieve/script.c#L666

strcpy(actions_string,"Action(s) taken:\n");

https://github.com/cyrusimap/cyrus-imapd/blob/master/notifyd/notify_mailto.c#L121

fprintf(sm, "From: Mail Sieve Subsystem <%s>\r\n", config_getstring(IMAPOPT_POSTMASTER));
fprintf(sm, "To: <%s>\r\n", options[0]);
fprintf(sm, "Subject: [%s] New mail notification\r\n", class);

Recently I was in the situation where I needed to manage users in Kolab from PHP.

There is an API for the Kolab Webadmin, and it is documented here: https://docs.kolab.org/architecture-and-design/kolab-wap-api.html

There is also a PHP class, that I could have used: https://cgit.kolab.org/webadmin/tree/lib/kolab_client_api.php. But for some reason, I am using CURL.

It took me some time to figure out how to do the GET or POST calls for connecting to the API and call user.info, user.delete, user.add and users.list.

Therefore, I have created a small PHP class, that shows how to do that.

You can find it here: https://github.com/TBits/KolabScripts/tree/KolabWinterfell/kolab-webadmin-api-client

There is also a test.config.php and a test.php to show the usage of that class.

During development, I sometimes got the message: “Internal error”. This is from the class kolab_api_controller, eg. https://cgit.kolab.org/webadmin/tree/lib/kolab_api_controller.php#n181

Actually, it would help if that error was logged to /var/log/kolab-webadmin/errors with some detail:

else {
    Log::error("API controller: Internal Error, ".$service . "_" . $method. " Post: " .print_r($postdata,true). " Get: ".print_r($_GET,true));
    $this->output->error("Internal error", 500);
}
