Understood. You are correct, of course.

Would you consider then the possibility of adding a tag to the message
metadata in the queue?

The idea is that different smtpd instances could tag the messages they
add to the queue with some user-configurable string, which would then be
exposed by the scheduler protocol. An SRS application could then inspect
the tag value and use it as one of the factors to decide if it will
munge the sender address or not.

The motivation behind the tag is to avoid the need for a lookup on the
sender address (which could even be in a different data store than the
redirect database).

Thanks,
Andre
