It is possible to separate the per-sender and other email streams, but that is a bit more complicated, because most people don't have your requireents. This uses sender_dependent_default_transport_maps, where all per-sender default transports share a customized Postfix SMTP cient with its own smtp_sasl_passwd_maps setting in master.cf, which has all the per-sender entries. The other email streams use the 'normal' Postfix SMTP client with only per-destination entries in smtp_sasl_passwd_maps. Wietse
