The only way to obscure the email address is to use a web form to send the
email. If you are using a simple mailto type link then there isn't any good
way to hide the address because it must be available to the visitor. With
the form, you can submit it to an asp page or some other page (php or
whatever) where the source code for the page is never available to the
visitor, so you can hide the email address that way.

There is another trick that works with email forms too. You can fake a
domain name if you control the web server.  Here is an example. First do an
MX lookup on a domain (any domain you like) such as bob.com,

bob.com MX preference = 10, mail exchanger = mail-01.name-services.com

mail-01.name-services.com       internet address = 66.151.151.105

Ok now with that information you can fake a bob.com address and have it
delivered to you. On the web server create an entry in the HOSTS file

mail-01.name-services.com       1.1.1.1 (your mail server's IP address)

On your mail server setup an alias for your domain so that it accepts mail
for bob.com as well. Now just setup a web form that uses a cgi or webbot or
whatever your forms use to send email and set the address to you{at}bob.com.
Presto, your web server will send it to your mail server but everyone else
in the world will resolve it to the 66.151.151.105 address so any harvested
addresses mailed from a foreign server will go to the wrong place.
