That's so we don't have to manually decode the base64 :)

That's because it's showing you the source, which may be base64.

Thunderbird isn't being 'used' to hide anything. It's performing its 
functions properly.

I just realized what you might be trying to say. It probably has to do 
with a certain porn spammer that encodes email addresses in the links.

I've started including the following message in my LARTs so the 
redirection of the links can be followed without reporting my email 
address back to the server.

The links include my encoded email address, which is reported back to 
the serverlogs at dns-forward.com - I've seen them.

Please use the encoder at http://howardk.moonfall.com/encemail.html for 
encoding your own address and substituting it for mine if you need to 
follow the link.

Encoding a tagged email address into this link will help you to see more 
of the domains used by this spam gang ;)
