going back to the OP...

if your purpose is to prevent those listing their email address on your guestbook from getting spammed, your efforts will most likely be a drop in the bucket.
The people signing your guestbook are probably already getting Spammed.

I have one site where I have One email address for contact and when I REPLY to that email, I use another username that is NOT posted on the web anywhere.

The REPLY address gets more Spam than the address posted on the website (obscured by Enkoder).

So my address is getting harvested by trojans and other things in User's Windows computers that are just going through their address books in Outlook.
