A great document on helping with this problem is: http://www.postfix.org/BACKSCATTER_README.html I work in the email defense industry, and this has become an exploding issue since the Google CAPTCHA was hacked, and also since most Google email services (googlepages and others) will receive an email regardless of if it's a valid user and then backscatter it out if it hits a nonexistent address. I'm not trying to blame it all on Google since this problem predates their email-based services, but they seem to be a heavy cause of the recent rash of complaints that I've seen on many other mailing lists that I monitor. -- John Evans Administrator of kilnar.com ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
