Requests were actually done in parallel with normal processing before,
just not as well.
Basically, the RBL stuff was nearly rewritten from scratch.
IP address improvements
- test more IP addresses (new Received: code, use a few more headers,
and various bug fixes)
- improved (and simple!) algorithm for dial-up tests
performance improvements
- use less CPU and network to do each test (avoid redoing work, only
do work when needed)
- dynamic timeouts
RBL selection improvements
- revised the list of RBLs after extensive testing (tested about 150
RBLs, although the final list is not changing that much)
- entirely new RBLs: SORBS, DYNABLOCK
- new sub tests: NJABL tests, OPM sub tests, more OSIRU sub tests
- these are gone, not that they were being used much before:
score RCVD_IN_RELAYS_ORDB_ORG 0.0
score RCVD_IN_ORBS 0.0 0.499 0.0 0.114
score RCVD_IN_MULTIHOP_DSBL 0.0
score RCVD_IN_UNCONFIRMED_DSBL 0.0 0.512 0.0 0.0
RBL functionality improvements
- RBL bitmask test support (used by OPM and RBL+)
- preliminary SenderBase support
- eval test to check From: hostname in domain-based RBLs
reporting
- log more information used in spam reports and an optional _RBL_
header token for add_header
- TXT query supported added (used for single RBLs that support it)
