Deleting the last highlight filter creates a 500

[LevitatingBusinessMan]

Hey,

I am really sorry bother you with issues like this. Let me know if anyone can reproduce this: When I delete the last "Message Highlight" rule it displays an "Oops... Something went wrong!" page. Internally it seems like a 500 error occurs.

Assuming this is indeed an issue at https://github.com/corbosman/message_highlight I am curious if we could maintain an in-house fork of that plugin (it's not maintained).

The message highlight plugin is fairly limited, allowing only a single rule at once only matching the subject, to, from or cc.

I found this plugin which is even older but seems like a stronger tool for the same job: https://github.com/binsentsu/message_label

Preferably I'd love to see a way to mark/highlight/label messages based off of the managesieve filters. Via the flags or via a header or variable or whatever.

I did some more research into different labelling/tagging/flagging options. But it's kind of out of the scope of this issue so I might open a new one for it.
