Smarthost/External SMTP
It would be nice to have an external SMTP (smarthost) ability for a per-domain basis (most mail services have this)
We use this for external scanning, data leak prevention and more.
Can this be be done?

You can do this with Postfix and Sender Dependent Relayhost Maps:

I'm not sure that is more than an edge case though.
