Every time I send a mail from business (Lotus Notes) to my Kopano Server (Univention) I get a Server Error (500) (Desk App and Web App). Attached the Mail (saved from Thunderbird). All other mails are received correct.
My Installation is on Univention 4.3-0 errata12 and the Kopana Versions are:
Kopano Core: 220.127.116.11
With very much help from the Kopano forum I figured out the following solution:
apt-get install php7.0-curl) and
apt-get install php-bcmath) and add the line
/etc/php5/apache2/php.ini (I don’t now, if this is necessary). Restart the server and the error messages are gone.
Maybe add this to the install routine
