Lack of interest Seperate Sending Emails

[The Dark Wizard]

I would like to suggest the ability to control which email comes from which address/SMTP. This includes conversations, watched threads/anything else xF sends an email out for, and most importantly registration.

With the amount of services for emails coming out by Google, Microsoft, Mandrill, and many others, and how costly they get, it would be nice to control exactly what gets sent from where.
