1. The configuration files in config/environments/—development.rb, testing.rb, and production.rb—are a good place to specify the settings that Rails should use to send outgoing mail.

2. A model class extending ActionMailer::Base containing a method that sets email parameters can handle all of the header information for email messages, and a view can define their content.

3. To send HTML email, the content_type must be set to text/html for simple HTML email, or to multipart/alternative for messages containing images, stylesheets, or other contents beyond the HTML.

4. Yes, Rails can check a mailbox to see whether anything has come in, and retrieve and process messages.
