Hello, When I send an email to invalid email, I got *550 5.1.1 The email account that you tried to reach does not exist.*
How can i get the message before sending? I connected to smtp.gmail.com:587 send command *RCPT TO: <invalid-email>* But I always get 250 message, until i send it out and get above 550.. Thank for your help. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
