Question

I’m creating a Mail object in a Rails app and want it to pick the mailer settings:

original = UserMailer.new_registration
original.deliver# Does the job

custom = Mail.new(original.to_s)
custom.deliver # Fails: OpenSSL::SSL::SSLError: hostname does not match the server certificate

Apparently the custom Mail object isn’t picking up the Rails settings.

Answer 1

Looking at the code, we can pick up the config from the mailer the following way:

custom = ::Mail.new(raw_email)
key = Rails.application.config.action_mailer.delivery_method
delivery_method = ActionMailer::Base.delivery_methods.fetch(key)
delivery_settings = ActionMailer::Base.send("#{key}_settings")
custom.delivery_method(delivery_method, delivery_settings)
custom.deliver
