We subscribe to the Spamhaus Domain Block List (DBL). We use that as part of a URIBL check which is nice, but they recently noted that it would also be useful to run the DBL against the following items:
- Sender domain (MAIL FROM) - HELO domain - Domain in rDNS of sending IP Blocking this stuff at SMTP stage in postfix would be straight forward, but generally we prefer to be liberal in what we accept and score it in SA instead. However I don't think it's actually possible in SA to run any of the above things against a RHSBL at the moment, or am I missing something? Rob Rob Mueller [email protected]
