Don't use mailto: Links
The original purpose of mailto: links was to allow users to click on a link on your website and send you an email, a very sensible idea.
Unfortunately these links now get abused by spammers who will harvest your email address straight out of the webpage and put you in a database of not so willing recipients of their spam emails.
There are plenty ways around the mailto: problem, some solutions are
- Use images instead of putting your email address in the page.
- Use a piece of JavaScript to add some Java code to the page that has the same effect as the link itself.
- Encode your email address and use JavaScript and reassemble it when needed so it cannot easily be harvested.
- Describe your email address to a human reader, so the spambots cannot see it.
