I agree, entity-encoded mailto: links work quite well. They may not work
forever, though, and some Drew McLellan made a good point

to spammers, as the very act of obfuscation could suggest
that the address is important to someone.
Once you put something out on the Web, it's availible for everyone to
read - and that includes spambots. If only people stopped buying
things from these spammers...
