+ Will "Show Spam Clues" notify a spammer that I opened their message?
+ --------------------------------------------------------------------
+ We think not (but we don't have the source code to Outlook to check
+ for sure).  In general, there are 2 ways spammers can determine this;
+ the first is via an automatic 'Read Receipt' (but this is unusual, as
+ the "from" address is generally forged so the receipt goes nowhere
+ useful).  The second common trick is by sending HTML spam that
+ references unique URLs (generally images) on the spammer's server.
+ When this HTML message is rendered, these fetching of these URLs 
+ identifies to the spammer the associated email address.
+ 
+ As far as we are aware, SpamBayes does not generate a "read receipt"
+ for "Show Spam Clues", even though the message is marked as read (and
+ we don't know how to prevent it being marked as read).  However
+ that if you are concerned about this, you are encouraged to configure
+ Outlook's generation of receipts manually.
+ 
+ Further, as "Show Spam Clues" does not attempt to render the HTML nor
+ otherwise contact any of the URLs in the message, this will not
+ register a hit on the spammer's server.
