Lack of interest Specify different mail methods for registration and notification

I switched to Amazon SES to ensure reliable delivery of email confirmations on new user registrations, but unfortunately the volume of email sent out for notifications on new conversation replies was racking up my SES charges to upwards of $45/mo (and that's with just over 2000 users).

It would be amazing to be able to just use the server to send out the notification emails, and use SES for the critical stuff (admin emails and confirmation emails).
