thank you for your help! If i understood you correctly, i set in transport:
domain1.de exchange: In master.cf exchange unix - - n - - smtp -o smtp_sender_dependent_authentication=no -o transport_maps=hash:/etc/postfix/transport_internal And in transport_internal domain1.de smtp:192.168.124.5:2525 but this way, postfix is doing a MX-lookup for domain1.de and not honoring transport_internal as it seems. Is this basically the right path? Am Di., 11.
