They will be detected by MS as not being a reply to a mail that went thru 
the system. I don't know if that means they get tagged as spam, I'm not 
using the feature. Just search the archives for "watermark" (or maybe 
"water-mark"?) for the various problems.
As Matt says, not all read receipts come from a NULL sender. But all that 
do will be subject to this.
