* [Fix] Prevent DNSWL sabotageMarc Dierksen2023-10-051-10/+10
| | | | | | | | | | | | | | | | When exceeding the query limit for DNSWL it can happen that instead of the returncode 127.0.0.255, that according to documentation (https://www.dnswl.org/?page_id=15) indicates a block, the returncode 127.0.10.3 is returned for all queries. According to documentation (https://www.dnswl.org/?page_id=15) the 127.0.10.3 returncode indicates the highest level of trustworthiness that should never be blocked and a category of 'some special cases'. As it turns out that documentation is a lie and that 127.0.10.3 returncode is used by DNSWL to intentionally sabotage email security by marking all sending servers as highly trustworthy (https://www.dnswl.org/?p=120).

* | [Minor] Align scores of Spamhaus DBL, SURBL, URIBL DNSBL symbolstwesterhever2023-08-021-12/+12
| | | | | | | | | | | | | | | | | | | | Given that they have about the same false positive rate, it makes sense to treat them equal in terms of scoring: - Particular threats (phishing, malware) are scored a bit higher than mere spam domain listings - "Abused legitimate" listings are scored lower for some DNSBLs already, this has now been aligned. - For SURBL, cracked and abused sites are treated with the same score.
* | [Minor] Increase score of URIBL_XBLtwesterhever2023-08-021-1/+1
| | | | | | | | | | This aids with detecting FQDNs hosted on hacked machines, such as used in Fast Flux-style botnet spam.
* | [Minor] Reduce score of URIBL_SBL_CSStwesterhever2023-08-021-1/+1
|/ | | | | | | Given that CSS is an automated component of SBL, this should not receive the same scoring as manually conducted SBL listings. Particularly for shared hosting environments, CSS hits on IP addresses derived from FQDNs sometimes were found to be scored a bit too high.
