Yep. But in my environment, that's my first-ever case (out of roughly
300,000 messages scanned in the past year) when URIBL_SBL hit a ham. Running
a corporate email server makes for a significantly different corpus than the
universe as a whole, and thus makes some different scoring sensible.

(But that's still no excuse for tweaking a rule score without realizing what
it's doing, and I have flogged myself appropriately for it.)
