Forum: Ruby on Rails How do I stop email from being delivered in the interceptor?

Hi,

I am developing a rails 3 application.
I want to use a interceptor before delivering emails.
If a conditions meets, I want to stop the email.
How do I do that?

Thanks.

When you say 'delivering' emails do you mean 'sending'?.
Is it the rails app that is sending the email?
If so how is it initiating the send.
Can you not just test the conditions before sending?

Have a look at the railscast for actionmailer in rails 3.  The last part 
of
the video is about intercepting
the emails so it gets sent to the address you specify in your config.

Sam, did you get a solution with an interceptor?  I tried returning 
false but the email is still delivered.

You can throw an exception in the interceptor.

I had the same problem, and stumbled upon this while reading the source 
code:

class MailInterceptor
  def self.delivering_email(email)
    email.perform_deliveries= false
  end
end

@jaden_c, I tried the "perform_deliveries = false" in my interceptor but 
the message still sends.

class CANSPAMInterceptor
  def self.delivering_email(message)

    ......

    message.perform_deliveries = false if message.to.size == 0
  end
end


Is there something else I need to know?
