Horde attachment file size limit



I am running up-to-date UCS server with Horde installed via App Center.
Now a user needs to send an attachment bigger than 2MB, for which the upload is denied.
In Horde Administration $conf[compose][attach_size_limit] is already set to ‘0’ (zero).
Therefor the limit for PHP upload_max_filesize is relevant.

But how can I get that changed so that it is persistent since Horde is running in a docker container?



Hi Jörn,

I thought, the standard limit is 10 MB. But a good beginning would be a look in the Univention Config Registry. Go to the Univention Management Console (Webbrowser) --> System --> Univention Config Registry. Search for “limit” or horde", there what should be to be found the useful.

Or with CLI:
ucr search limit

sample set parameter for 20 MB:
ucr set mail/messagesizelimit=20480000



Hi Dirk,

I already had a look there. Since Horde is dockerized not much parameters found there.
Also via App Settings there are no parameters available to customize the settings I am looking for.

Wanted to disable some of the Horde applications like task manager (nag) or file manager (gollem). Only way I found was entering the docker container and changing configuration there. But those changes are not persisted, due to docker.
Docker requires config changes to be provided from outside of the container.
