Plugin for WordPress 2.5
The plugin should add three additional options, to the Awaiting moderation section of the WordPress 2.5 Comments management. Each of the three options, when chosen, should delete the comment in question, and automatically send an email message containing one of three (one for each option) predefined text strings, explaining why the comment wasn't approved. In addition to the predefined text, the email should contain the original comment, to which the email is associated.
The plugin doesn't need an administrative interface. The text strings may be defined directly in the plugin file.
