How to use MailCatcher in Rails

I have had an opportunity to use MailCatcher. So, I summarize it in order not to forget it. MailCatcher enables you to set up a local SMTP server. If you want to try out mailer functions in your application, I recommend this. It is so easy and effective.

  1. Install gem

2. Write port number, address and domain

3. Start mailcatcher

4. go to mailcatcher
