Why not add Spamhaus' XBL zone lookups?
(Ryan replied:)
The thought had only briefly crossed my mind. Is XBL really a good resource for SURBL classification? I thought XBL just listed exploited systems and open HTTP proxies. Hmm. I suppose I could just code it up and run it on a bunch of mail to see what happens... Or I could just use the combined sbl-xbl.spamhaus.org list, I suppose.
I would really only use SBL, if you check agains XBL you could also test on DSBL, but we want to get the hardcore non-proxy spammers. The zombies are stopped with DSBL/XBL and alike anyway. Any thoughts?
Yes, there was perhaps some confusion about what Alex meant in suggesting XBL. If he meant use it to check headers then I agree it's a useful way to spot zombie and open server usage. If he meant to try XBL against spam URIs, then I agree it probably won't do much.
