Outlook 2000 Rules Wizard

Hi

Here is what I'm trying to do:

Currently I have a rule that replies to a certain sender with the message "E-mail Received" in the body of the text.

Now they inform me they need the subject line of the e-mail they sent me to be in the subject line of the e-mail I reply with. They still need the text to say "E-mail Received".

I was going to automatically forward the message back to them, but it has attachments and they would end up getting sent back.

The Out of the Office rule does this but I can't find a way to modify it.

Any help?

Thanks
