Internal Server Error (500) in DeskApp and WebApp displaying a Mail from Lotus Notes with Signiture

Hello,
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.
thank you and regards
Stephan Geberl

Update: A Foreward - Mail of this Mail from my Tuch-Down (Mobile) - Client to the same Mail-Adress is readable.

Hi @sgeberl ,

I took your email and delivered it on a Debian 9 system vie kopano-dagent (e.g. kopano-dagent user1 -f 1264.txt). For me the mail displays fine in WebApp (and DeskApp should be no different).

What kind of System are you running? which version of Kopano/WebApp/etc)? What is logging in the webserver at the time of the error 500?

ps: this forum is using markdown formatting. please use code blocks when pasting log messages or larger chunks of data.

Hi @fbartels,

thank you for your answer. My Installation is on Univention 4.3-0 errata11 (also debian) and the Kopana Versions are:
WebApp: 3.4.2.1108+36.1
Kopano Core: 8.4.5.0
Z-Push: 2.3.8+0-0
I permanently get the following error opening the mail (picture).
0_1523469679034_85d219eb-cd74-44b2-b334-08ef8bef3427-grafik.png
Maybe this is the relevant log (/var/log/apache2/error.log):
Thank you in advance
Stephan

@sgeberl said in Internal Server Error (500) in DeskApp and WebApp displaying a Mail from Lotus Notes with Signiture:

Call to undefined function curl_init()

It seems you’re missing php5-curl or php7.0-curl module on your apache server

rg
christian

Yes, @externa1 is correct. That module is required by the enabled S/MIME plugin in your installation.

Thank you very much, I will try to install this, test and inform Univention
Thank you,
Stephan

The solution was to install php7.0-curl (apt-get install php7.0-curl) and php-bcmath (apt-get install php-bcmath) and add the line extension=curl.so to /etc/php5/apache2/php.ini (I don’t now, if this is necessary). Restart the server and the error messages are gone. Now the zertificate is shown to me as revoked - this I have to figure out with the sender.
Thank you for showing me the right way
