Yes, the mailto can also be encoded. Doesn't matter though, because it's 
constant.
I just wanted to add that obfuscating could be done easily by a 
mediawiki filter such as

http://www.mediawiki.org/wiki/Extension:EmailObfuscator (uses the ascii 
code method)
http://www.mediawiki.org/wiki/Extension:EmailAddressImage (replace 
address with Image)
http://www.mcmilk.de/wiki/Wiki_EmailTag (image as well)
