If I look over the messages in my spam box for the past 2 weeks (from 20080201
to today), and checking the rules they hit when they arrived, I get 39 hits on
my spam for RCVD_IN_DOB, out of 48198 messages!  that's a 0.08% hitrate, which
correlates with comment #4.  so that rule is not much use.  

The same is true for DNS_FROM_DOB; 39 hits, and I suspect they're the same
messages (although didn't bother checking).

however: URIBL_RHS_DOB hits 13936 out of 48198.  that's pretty good, 28%.

I've just noticed -- it was not set with #reuse.  THis is now fixed, so the
accuracy rates in ruleqa.spamassassin.org should start working for that rule:

: jm 180...; svn commit -m "oops.  URIBL_RHS_DOB and URIBL_RHS_AHBL need #reuse
so that their accuracy is measured correctly" rulesrc/sandbox/

Sending        rulesrc/sandbox/jm/22_bug_5667.cf

Committed revision 627159.

I've removed the other rules from trunk, since they aren't hitting enough to be
worthwhile:

: jm 194...; svn commit -m "bug 5768: actually, remove DNS_FROM_DOB, RCVD_IN_DOB
and __RCVD_IN_DOB entirely, due to low hitrates" rulesrc/sandbox/jm/
Sending        rulesrc/sandbox/jm/20_dob.cf

Committed revision 627162.
