Hi!

So, as you may be aware, we have a minor issue in terms of figuring out
which whitelisted domains should be skipped in queries.

  SpamAssassin now ships with list of domains that are excluded for
  SURBL lookups from the SURBL whitelist.  This list is the 125
  most commonly queried domains.

Why not make the SURBL whitelist into a DNSBL? I'm assuming that the
whitelist has something to do with correctness of results. Or is it just
to reduce the number of queries?

IT was mainly to reduce hits on the nameservers. On all SURBLs the whitelist is used allreayd so for lookups it would be a waste to do a extra lookup. Doesnt bring much extra, or would you like to add a negative score for whitelisted domains? Then it would make sense. But on the other hand then spammers will add random links with whitelisted domains, since the whitelist is publicly available.


Bye,
Raymond.
