Expand the ability to add customized messages to this addon. Example:
"This message is SPAM, remove my address from your list"
OR
"Stop sending me mail that doesn't apply to me"

I would like to have a few more features. The ability to:

1. add some customized messages,
2. auto reject by email address and set a default message for that address, and,
3. eliminate (optional) the boilerplate message at the end.

The button appears and absolutely nothing happens. I also would have written first but there is no contact form. This one is an immediate uninstall.
