MailHog VS Exim

hey HN, I recently published an article going deep into email previewing (in Ruby on Rails, but I think it's relevant beyond Rails).

MailCatcher (https://github.com/sj26/mailcatcher) and MailHog (https://github.com/mailhog/MailHog) are super handy and easy to run locally. Both spin up an SMTP server which you can direct mail to, and give you a nice web interface to browse mail and preview it.

Happy to answer any question! thanks, harrison

depends on the infrastructre setup, but if you're able to specify smtp server the backend will use you can you something like https://github.com/mailhog/MailHog or https://github.com/rnwood/smtp4dev to catch any sent email, regardless of email address and read it via the respective api. Both mailhog and smtp4dev have decent api documentation.

I found https://github.com/mailhog/MailHog for SMTP to and Webinterface and https://poste.io/ for easy mailserver.

To test email sending locally, you can use the mailhog service.

We are almost ready to test our plugin. However in order to properly do this we would need an SMTP server since our plugin sends emails. You could use some real SMTP server. But that would likely cost money and you will have to use a real email. It is much easier to use a mail trap service like MailHog.

For development, we have deployed a instance of MailHog to our cluster, a simple mail server that catches all mails without forwarding them. It allows any user/password combination. Here is what our mailhog controller looks like:

I use MailHog for testing when I don't need a full email server https://github.com/mailhog/MailHog
