"transport_maps" looks into a *map*, and a map in Postfix is more than just DB. For example it can be a *TCP table*, which means Postfix is asking some program that listens on a specific port for the key, and gets a value in return. It is described here: http://www.postfix.org/tcp_table.5.html Seems like this can be a solution for you. You have of course to write the appropriate program that replies with the correct server address depending on recipient's email adress. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub."
