Protecting Your Email Address with an Anti-Spam Encoder
You Don't Want Spambots Grabbing Your E-Mail Address?
One alternative is cgi forms that use server-side software to process contact forms. It's a good solution because the software containing your e-mail address is inaccessible to the spambot, but it's more trouble than I recommend for a personal site or a site that has lots of mailto: links.
Or you can transform your e-mail address into html "character entity references" that browsers can translate into human-readable content, but simple screen-scrapers can't.
You can manually translate each character in your e-mail address. Or, use the NATATA Anti-Spam Encoder to do it automatically with an entire website at a time.
