We have translated "mail notification messages" file. This file is located under /opt/zimbra/conf/msgs/ZsMsg.properties.

However, new messages are not used in any case. We have tested:
- Creating a new file called ZsMsg_es.properties, but no changes.
- Replacing ZsMsg.properties with new ZsMsg.properties translated, but no changes.
- Modifiying original ZsMsg.properties with several changes.

But now changes are displayed when receiving mail notifications.
Of course, zimbra has been restarted to apply new changes.

So my question is:
How do I modify ZsMsg.properties file? Is this file still used for mail notifications literals?

Thanks in advance.
