If the IPs sending "MAIL FROM: @yourdomains" have matching A and PTR records, then put yourdomains in from_senders_mybogus > and domains? And >if a user sends mail from one ISP but receives mail here should I list their >domain? any msg "MAIL FROM: sender.domain" in from_senders_mybogus and from_senders_bogus must be sent to IMGate from an IP with matching A + PTR records. Else, it's considered a forgery of the sender.domain. >ie. >mydomain.com >mail.mydomain.com >customer.com >mail.customer.com you don't need the "mail" subdomains. Len
