Spammers could add some fake URIs like yahoo.com, gmail.com,
microsoft.com to their spam runs so that their mails get a hammy
score(if surbl gives a negative score using some whitelisted URIs).
Also, spammers could use a badly configured good intentioned mailing
list like sourceforge.net or through services like yahoo.com, gmail.com
etc could reduce the accuracy. Having a grey +ve score for URIs queried
from MTAs with patterns matching a spam run is a nice idea though.
