Spam filter that blocks the spam senders from RECEIVING email!

Posted on Wed 26 March 2008 in Spam wars

Interesting, I just tried to report spam to a company who I assume ran the campaign in good faith. The report got an unexpected response:

: host lonvs07.kinexus.net[212.113.24.167] said: 554
    Service unavailable; Client host [89.234.3.158] blocked using
    relays.ordb.org; ordb.org was shut down on December 18, 2006. Please remove
    from your mailserver. (in reply to RCPT TO command)

Panic! One of our server IP's got blacklisted as a spam source!..... phew, not the case (thank you slashdot), emailiq are filtering their email for spam using a blacklist database that shut down over a year ago. The blacklist have decided they gave enough notice to people filtering against their list, so from now on they are reporting every email checked as being spam. If you're not getting email today, better check with your mail provider.

This company may not have meant to send spam, but because of spam they now have no email until the reconfigure their servers. Events like this show just how much spam is really costing everyone.
