Receiving an email with a gzip attachment, gets an extra gzip later  
added to it when downloading the file.
I have confirmed this using firefox/opera/chrome browsers, all latest  
stable releases.
I have also confirmed this using normal apache 2.2 config, and with  
lighttpd (no compression enabled on lighttpd)
