Rails Mailer: sending emails to a local file

Question

Is there any way to send emails in rails 3 to a local file or so, instead of using an SMTP server? I\'d like to test the email\'s contents without using any kind of SMTP, ideall

Answer 1

There is also the letter_opener gem which will save mail to disk and open it in a browser.

Or mails_viewer which has a Web UI to view the emails instead of opening them in a browser.
