receive(raw_mail)
public
Receives a raw email, parses it into an email object, decodes it, instantiates a new mailer, and passes the email object to the mailer object’s receive method. If you want your mailer to be able to process incoming messages, you’ll need to implement a receive method that accepts the raw email string as a parameter:
class MyMailer < ActionMailer::Base def receive(mail) ... end end
