Are you running a caching name server locally on the machine? This helps alot in reducing the DNS traffic for RBLs and URI RBL's.

I normally process emails in under 2 seconds using couple of RBL's, pyzor and all of the subl.org URI lookups.

Greetings:

SURBL does not appear to work with network tests totally disabled (i.e. using --local in the spamd startup).

No network tests:

        0.1 to 0.6 seconds to score emails as spam or ham
        Approximately 90% accuracy on tagging spam correctly
        Approximately 2% false positives tagging ham as spam

Network tests (for SURBL)
        11.0 to over 16 seconds to score emails as spam or ham
        Approximately 95% accuracy on tagging spam correctly
        Approximately 1 to 2% false positives tagging ham as spam

Thanks to input from this mailing list, we've disabled almost all of the network tests.

This has helped tremendously brining the scoring time down to an average of 3 to 4 seconds per email with the range of times from 0.4 seconds to 8 seconds.

Thank you.

Or you could boost the SURBL scores, or lower your spam
threshold.  :-)
