That's assuming, of course, that Slim Devices sends email from the same IP address where they receive it. In Slim Devices' case it happens to be true (at least it was for the one email I've ever received from Support) but it's not really a safe assumption in general. I would hope that any tool that helped you look up an MX record for the purposes of determining if an organization's *sent* email would be subject to blacklisting would mention this caveat. These days spam is far more likely to come from one of zillions of compromised PCs on broadband links than from accidentally mis-configured corporate mail gateways. Given that, the whole idea of blacklisting spam emitters is questionable since it no longer serves as leverage to get the person responsible for the host to close the hole. Now blacklists serve only as directories of potentially available relays for spam senders. (Yes, spammers do use these blacklists this way) Of course, the operators of these lists are now quite invested in them and aren't really open to the idea that they may be anachronistic and doing more harm than good. -- rudholm ------------------------------------------------------------------------ rudholm's Profile: http://forums.slimdevices.com/member.php?userid=2980 View this thread: http://forums.slimdevices.com/showthread.php?t=21998 _______________________________________________ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss
