I'd like to share my success ASSP deployment that has the feature "domain-based email routing": Inbound Connection: Internet mails -> Postfix-1 (SMTP Gateway) -> ASSP (SMTP Proxy) -> Postfix-2 (domain-based email routing enabled) -> Email Server1/2 => I use the feature "multi instance" of Postfix for the feature "domain-based email routing", where as: * Postfix-1 (primary instance): Accept all incoming messages from the Internet, then route them to ASSP * Postfix-2 (secondary instance): Used for ASSP as the SMTP destination configured in ASSP * Postfix and ASSP are running on same host on my System Regards, N.
