spamassassin-users: DNSWL will be disabled by default as of tomo

DNSWL will be disabled by default as of tomorrow

Tomorrow's sa-update will include disabling of the DNSWL rules. If you
wish to locally enable them with the same scores which had previously been
default, use this:

score RCVD_IN_DNSWL_NONE -0.0001
score RCVD_IN_DNSWL_LOW -0.7
score RCVD_IN_DNSWL_MED -2.3

It was disabled because it is returning a value triggering RCVD_IN_DNSWL_HI
for all queries from DNS servers deemed abusive, causing false negatives in
SpamAssassin. It was the only network test, enabled in SpamAssassin
by default, intentionally returning known incorrect values under any

It is recommended that you use a local, caching, non-forwarding DNS server
with SpamAssassin:
This should prevent you from being considered abusive by DNSWL unless
you are actually doing multi-million queries per day, based on the list
DNSWL provided yesterday of who is currently categorized as abusive:

> * Google Public DNS servers (multi-million queries per 24 hours, no
> response from Google contacts)
> * Some big hosting provider resolvers:,,
>,,, (multi-million
> queries per 24 hours, no response/action from abuse@ and similar
> contacts)
> * Five single hosts with multi-million queries per 24 hours with no
> response/action from multiple contacts.

Problems have only been occurring when people use the above DNS Servers.
