Hi,
The book does not discuss sending email from EC2, and I don't believe there is a good solution for doing this without using an external service or email server. The recent announcement of Elastic IP addresses (static-like addresses) might help somewhat, but it is still not possible to configure everything that is necessary to avoid a proportion of the emails sent from EC2 from being flagged as spam.
The best place to look for suggestions and advice on this topic is the EC2 discussion forums, but as far as I'm aware there are still limitations in EC2 that make it ill-suited for email distribution.
