Take for example GoDaddy's hosted email service.  They are using a 
local, outdated copy of SORBS that has one of my personal servers listed 
in it.  It was an open proxy for about week nearly 3 years ago and still 
they have it listed.  The upside is that I've demonstrated GoDaddy's 
email incompetence to potential customers and gotten them to switch to 
our own mail services.  Their loss, my gain.
