Not that this really answers the question, but I'm a little wary of using
mailto: URL's *anywhere* anymore. The instant you put an email address on
a web page as-is is the same instant you get added to a pile of spammer's
lists. Most of them use web-crawling bots to harvest addresses. We've
got an amusing Apache mod_rewrite + Perl script combo that defeats most of
Just something to think about.
http://www.turnstep.com/Spambot/avoidance.html has some interesting
suggestions for getting around it -- keeping the email address out of the
creative use of tables, putting the address into a .gif, and so on...
