Results from 4/9/2011

* Recent results indicate 1.3% FP rate on the past week of ham, ranging up to
2.5% FP's in recent weeks.  This is worse than our measurements in January.
* 88% spam overlap with RCVD_IN_MSPIKE_BL.  (Most likely the only new DNSBL to
be added to spamassassin-3.4.  Look at its stellar spam detection performance
with almost zero FP's!)
* 83% spam overlap with RCVD_IN_HOSTKARMA_BL.
* 63% spam overlap with RCVD_IN_PSBL.
* 62% spam overlap with RCVD_IN_PBL.

>From multiple months of analysis showing roughly the same thing, it seems clear
that UCEPROTECT is a little too unsafe and redundant for spamassassin users.

I suppose we can remove it from masscheck for now.  But I'd like to measure it
again every few months to see if it has changed any.  I like being able to
definitively warn people against stuff like this with fresh data.
