Hi,
I must have been searching at the wrong place or using the wrong
keywords as I have been trying to find how to correctly transport to a
particular smtp relay or have postfix do a MX query based on the "from"
address field. I did look at the postfix doc, in se's and the
postfix-users archives withtout any luck. The transport maps do a great
job of doing it based on the "to" address field or domain but I am still
looking to find how to do it with a "from" field. I hope someone can
point me to the right doc.

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
