Capture development emails with Mailpit

[gshaw]

My preferred way to capture and view emails being sent by a Rails app in development is to use Mailpit. It runs a local SMTP server at port 1025 and a barebones email client at port 8025. I used to use MailHog but development has stalled. Mailpit has the same ease of use while supporting newer features and looking nicer.

The mailpit utility can be installed with brew:

brew install mailpit
brew services start mailpit

The development smtp settings are configured in config/environments/development.rb:

config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = { address: "localhost", port: 1025 }

All outgoing email from the development server will be captured and viewable in
both html and text form at localhost:8025.
