Feature Request: Managed SMTP service (like AWS SES)

I'd love it if Linode had a managed SMTP service so that users can send emails on it and get information back regarding bounces and spam reports to make sure that they have a healthy mailing list.

I initially thought about running my own SMTP server but quickly came to the conclusion it would be a nightmare to keep up and running and that I'd rather pay someone else to handle it for me.

I'm sure there are lots of other people who would appreciate this service.
