That is an interesting picture. It looks like dropping the pregreeters
made your reject rates already go down quite a bit. Of course it
is known that spammers prefer to use secondary MX hosts because
these hosts often serve many domains and therefore have more
permissive settings.
This weekend I finally found time to update the non-production
release. This version should support "no DNS blocklists" without
panic, and it also has better support for "postfix reload".
There are still plenty of rough edges. It does not yet remove entries
from the btree database so the file needs to be renamed periodically,
and it does not yet log the sender/recipient of rejected mail. For
that reason alone I don't recommend turning on DNS blocklist lookups
except for gathering statistics.
I'm still open for program name suggestions. If someone has a better
name than "swatter" or "halligan" let me know. Once the name changes,
all the configuration parameters will change, too.
