Hi,
Recently we had a complaint from a user that email addresses were  
being exposed in the listen archives.  So I have now rigged in an  
obfuscation function in listen that will obfuscate addresses in the  
from, subject and body of messages for display purposes.  We now have  
to decide how we want to obfuscate.  What's the best way to do it for  
the least amount of trouble.  I've read up on encoding methods,  
replace('@', '<at>') methods, javascript methods and the google  
"cabra...@..." method (in which the ... is a link to a  
captcha).  I think the google method is probably the best but it is a  
bit of a pain to implement and requires a captcha engine.  So, any  
votes?  See http://www.alistapart.com/articles/ 
gracefulemailobfuscation for a good overview of the various options.
