You can configure customized SMTP clients in master.cf, each with an appropriate smtp_bind_address setting, and use transport_maps to choose between those clients. Thanks Wietse. other than binding multi-IP on a same host, is it better to have multi-geobased-MTAs for incoming messages?

A small improvement: instead of transport_maps, one could use a FILTER action in check_policy_service, SMTP server acccess table, or in header/body_checks.
