Multiple smtp servers feature idea?

Hi everyone,

So I have 3 email addresses which helps me keep track of what is happening. ie. Info@domain is for clients only, supply@domain is for supplier communication and user@domain for more personal interaction with issues relating to aftersales.

I would love if I could select from which email my manager should mail from, alternating between quotes/invoices and purchase quotes/invoices.

Would this be a possibility in the future?
