Is it possible to configure different deferred mail delivery settings based on the domain the message is going to? In our case, for generic messages being relayed out to the world, the defaults are fine. However, for messages being relayed to our internal application, we require a minimal delay between failed message delivery attempts. (On the order of 15 seconds.) I found the tuning configuration options on this page: http://www.postfix.org/TUNING_README.html#hammer, but it looks like those settings are global. Can they be set per domain or would I need to set up a second Postfix instance?
Thanks, Drew
