Very nice one Josh!

Just one little improvement:
Put the subject of the AutoReply Mail also in the language file.
Maybe this one could be enhanced to send the mail to different recipients depending on the problem type?
Different AutoReplies for each problem type would also be an nice thing. I get many mails regarding the "invalid host" error message. The auto-reply could provide instructions for NIS etc.
Would be some kind of support ticket system, but it would save a lot of time i think.
