Feature custom message when blocked

[gaalos]

Steps to reproduce

1. Add rule like file zise rule
2. send file
3. get blocked by your rule

Expected behaviour

have a message that corresponds to the blocking rule

Actual behaviour

Just got access denied message or forbidden

This is not a user-understandable message

Best regards

This is also really my main issue with the app. The featureset is pretty nice but whenever you actually get blocked, the message looks like a technical error - both on the web interface and via WebDAV.

Without a proper message it is not really possible to use this feature unless everyone knows that it's there and precisely what it does.
