mocksmtpd: A "mock" SMTP mail server in Ruby

It’s in Japanese, but mocksmtpd is a “mock” SMTP mail server written in Ruby for receiving mail.


Thank you for introducing mocksmtpd.

I wrote gem version, and English document. If you interested in, please see:

We use web service in developement and staging environment. It is platform-independent and doesn’t require you to run your own SMTP.

It offers:

  • All emails in one place
  • Shared access for dev team to the inbox
  • Developer tools to analyze emails
  • Flexible configuration
