How does this system prevent you from sending challenges to forged from addresses? Doing so could/should get you on a few blacklists. Picture a few thousands spams all with the same forged from address being sent to your org and then getting challenged....Not giving you a hard time, just a heads up.
From: Jacob [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 06, 2008 12:41 PM To: NT System Admin Issues Subject: challenge/response SQL based white list We are looking at different solution for spam protection. What we are looking for a solution that can challenge/response an incoming email based on a white list that is SQL database based. For example, when an email is inspected by the firewall, the firewall can query a SQL table to allow the email to continue. If it does not find the email address in the SQL table, then challenge the email. The SQL table contains all of our customer email addresses and is updated consistently. I would figure Exchange server would have this feature, but I guess not: http://blog.tmcnet.com/blog/tom-keating/microsoft/exchange-server-2007-spam-whitelist-rant.asp Anybody have any suggestions they have uses/tried for white list centralization?
