Can the SBL also block domains? What is "URIBL_SBL"?
SpamAssassin includes rules for this purpose. They are URIBL_SBL and URIBL_SBL_A:
- URIBL_SBL checks if the IP of the authoritative nameserver of a given domain is listed in the SBL.
- URIBL_SBL_A checks if the IP of a given hostname is listed in the SBL.
- URIBL_SBL_A was introduced in SpamAssassin 3.4.3
Our SpamAssassin plugin retroactively enables 3.4.0 and 3.4.1 to use the same rules.
