Actionmailer SMTP Server Response

Question

When sending mail through actionmailer, the actionmailer gets a response from the SMTP server, when its ok, or when its wrong. Is there a way to retrieve this response after

Answer 1

Set return_response: true in the smtp settings and call message.deliver! instead of deliver. This returns the SMTP server response, a Net::SMTP::Response, which contains the server response you're looking for.

If you need a log of all responses from the connection with the server, not just the final result, you'll need to dig into Net::SMTP.
