Yes, it is "a" "common" place holder... But for how long????? Shouldn't a company be on top of that based on the type business they are in? Lookup those IP ranges to see if they those ranges are listed on any list; use DNS that is also not listed on any URI lookup? Normally, what... 7 to 10 days max for have a REVDNS to populate? Have you noticed now... The REVDNS now shows .declude.com (ironically after I mentioned it)? When did their move occur... Over a month ago? Yes.
That's not what I said on the REVDNS alone Sandy. What I said was: "...dotted/dashed IP address used by most.... filters and external filters to detect the dotted/dashed IP" "Whitelisting based just on a to/from/return address is not enough as these can be forged. In the past we used both the to/from/return address AND the REVDNS as the "whitelisting"." --------- More important, why would you think that whitelisting based on the REVDNS domain of a known and targeted anti-spam company would be trustworthy? --Sandy -- ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. mailto:[EMAIL PROTECTED] ------------------------------------ -- --- This E-mail came from the Declude.JunkMail mailing list.
