Here's a few examples:<p><a href="https://www-user.tu-chemnitz.de/~heha/email.en.htm" rel="nofollow">https://www-user.tu-chemnitz.de/~heha/email.en.htm</a><p><a href="http://problemkaputt.de/email.htm" rel="nofollow">http://problemkaputt.de/email.htm</a><p><a href="https://www.gaertner.de/~neitzel/email-to-mn.html" rel="nofollow">https://www.gaertner.de/~neitzel/email-to-mn.html</a><p><a href="http://www.karo-electronics.de/448.html" rel="nofollow">http://www.karo-electronics.de/448.html</a><p>...and of course there's this:<p><a href="http://arc.pasp.de/" rel="nofollow">http://arc.pasp.de/</a>
