My mail server has a lot of spamtraps. They come from various sources, but
one of the most prolific is bad addresses in personal domains. Several of
my users have their own domains, such as my own johnlevine.com, in which they

wipes and restores everything else.
Given the propensity of Windows machines to become overrun with malware,
rogue toolbars, cramware, and other unwanted annoyances, a way to get rid
of it all quickly seems like a great idea. But ...
