Action Mailer -- Easy email delivery and testing

Action Mailer is a framework for designing email service layers.  These
layers are used to consolidate code for sending out forgotten passwords,
welcome wishes on signup, invoices for billing, and any other use case that
requires a written notification to either a person or another system.

Action Mailer is in essence a wrapper around Action Controller and the Mail
gem.  It provides a way to make emails using templates in the same way that
Action Controller renders views using templates.

Additionally, an Action Mailer class can be used to process incoming email,
such as allowing a blog to accept new posts from an email (which could even
have been sent from a phone).

This is for Ruby on Rails 7.2.
