FiveTenSRCI assume you are refering to result code of 9. That usually means that they use wide search criteria to list addresses. Usually this means they block a /24.
I have seen a big uptick on this returns here from fivetem-misc: http://www.five-ten-sg.com/blackhole.php: misc - Miscellaneous includes (but is NOT limited to) the following groups. Note that this does NOT include misc.spam which is listed under spam above. 1) /24 blocks of addresses containing systems that are apparently sending bulk email (in volumes apparently comparable with the volume from AOL, Earthlink, Google), with any of the following attributes: missing or bogus reverse dns, reverse dns names in domains with no web server, or domains with boilerplate web content. 2) Systems that are strongly suspected of being multistage open relays (where I have not been able to identify the input stage) or open proxies. 3) Any system that delivers spam here, that appears to be running MS SMTPSVC, and that appears to have relayed the message from China, Korea, Brazil, or any known open proxy. These are generally systems that have enabled the guest account, and spammers are using them as open relays, even though they do require SMTP AUTH. Enabling the guest account allows anyone to relay thru them. ----- Original Message ----- From: Sharyn Schmidt To: declude.junkmail@declude.com Sent: Monday, February 12, 2007 7:10 AM Subject: [Declude.JunkMail] FiveTenSRC Hi, I was looking up a mailserver IP address in the DNSstuff's spam database link and noticed that the mailserver in question was listed on the FIVETENSRC spam database. Underneath the listing, though, it said in parenthesis, do not use. Is this not a valid test anymore? Thanks, Sharyn --- This E-mail came from the Declude.JunkMail mailing list.
