Sometimes clients just won’t accept the advice to use a contact form, and instead insist on having their email address on the site. This, of course, is just an open invitation to spambots scraping the address straight off the site.
A simple solution is to use javascript to mask the address thus fooling the cheeky little bots:
var username = "[your_username]";
var hostname = "[your_mail_account_domain]";
var linktext = username + "@" + hostname ;
document.write("" + linktext + "");
