You should be able to handle this with normal sendmail anti-spamming filters: If machine A is acting as proxy for machine B, then: allow B's IP to send mail to any domain by adding it's IP in the allowed IPs list. Add B's domain in the allowed domains for relaying. At B, add the domain in variable w (eg, Cw domain.com), but do not publish it in DNS. Hope it helps! Regards!
