Linux Development SMTP Server

Question

Everyone, I am looking for a good SMTP server for my development machine. I am running Linux mint 10. I need a good SMTP email trap that will listen to the localhost port and intercept all email originating from Ruby on Rails applications I am developing on without relaying them out to the world. The app needs to allow me to open and view the emails so I can review the test emails that are being sent.

I ask because when I worked on Windows there were tons of little applications I could install which would listen on port 25 and gather all the email sent from my applications as I developed and tested them. These little apps would allow me to open the emails after receipt so that I could verify the content of the emails. I need something like that on Linux (Mint 10 to be exact).

Advanced Thanks

Answer 1

All SMTP servers for linux can queue your mail if you dont tell them how to send the data on. I use exim, all the files for this and sendmail are stored in text format, so are very readable. So, both should suit your needs (sendmail comes with every distro Im aware of)

Answer 2

MailCatcher is a good option if you want something running locally (especially if you already have ruby). It presents caught mail via a web interface. Very simple and easy to install. You then just configure your app to talk smtp to a different host/port (like in the mailtrap answer)

I may be late to the game, but fakeSMTP is a really nice and easy to use, open-source and cross-platform tool.
