Summary: FH_HOST_EQ_D_D_D_D tests causing increase in FPs
Product: Spamassassin
Version: 3.2.0
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P5
Component: Rules
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
We are getting heaps of false positives off these rules - ironically
mainly from our IT services dealers/sellers/etc.
Since upgrading from SA-3.1* to 3.2.0, we have discovered that it
appears most small New Zealand businesses run mail servers on DSL links
with PTR records of the format "NN-NN-NN-NN.isp.carrier.nz". Hence they
end up with 2.2 points
(FH_HOST_EQ_D_D_D_D,FH_HOST_EQ_D_D_D_DB,RDNS_DYNAMIC) added without any
real effort. That plus their sputty HTML mails pushes them into the 5-7
range.
I know SA isn't really doing anything wrong, but it may imply the default
scores are too high? Justin Mason wondered if FH_HOST_EQ_D_D_D_D may be
overlapping the job of RDNS_DYNAMIC
BTW I have lowered the score of FH_HOST_EQ_D_D_D_D to 0.5 on our systems to
compensate.
Thanks!
Jason
