Rails Mailbox

Routing Inbound Emails

• Define all routes in app/mailboxes/application_mailbox.rb using the routing DSL
• Prefer scoped routing via sub-addressing (+tag) to simplify mailbox matching
• Use descriptive class names matching route targets (e.g., SupportMailbox, BillingMailbox)
• Never create a mailbox class without a corresponding route

Mailbox Class Structure

• Each mailbox inherits from ApplicationMailbox
• Implement the receive method to extract data from the inbound mail object
• Avoid side effects in parsing logic; keep extraction and persistence separate
• Always authenticate or verify the sender before performing sensitive actions
