Hi Etienne, We have been looking at a similar type of functionality but are using the client IP address instead. The two options we looked at both set the envelope recipient address using "+xxx" to encode the sender information which could then be used by a prce/regex transport map to send the message to the correct place. Either a policyd or a header_checks content filter would work. We are going to use the policyd to avoid processing a large data stream. Let me know what you end up doing and if you find any other options. Regards, Ken
