qpsmtpd VS MailHog

I used a proxy like this for a few years, though in my case it was to handle spam.

I based my work on :

http://smtpd.github.io/qpsmtpd/

I'd reject spam at SMTP time, but also capture the bodies of all messages that were rejected so that users could view them in an online quarantine. Worked pretty well, though I think these days the original perl-based project has been reworked into a nodejs thing:

I use qmail with qpsmtpd as a custom SMTP front end, I don't play with it now but I used to try different techniques and keep stats on what worked and what didn't (eg greylisting, blocklists, advertise AUTH LOGIN with a 250 header and ban anyone who actually tries to use it) and then I have my own custom forwarding and routing of dynamic usernames etc.

Ah the famous [email protected] email addresses we used to use in our test scripts to avoid sending email to anyone by accident. If we need to test the contents of the email then we use Mailhog these days. Can’t recommend it enough.

Mailhog

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

https://github.com/mailhog/MailHog This is set up for our test environments. Worth looking into

Does it say it's being send on localhost or on production? How is it "saying" it's being sent. We just setup mailhog to test emails for local development.

They should definitely invest in a chaos monkey (like Jim https://github.com/mailhog/MailHog/blob/master/docs/JIM.md)
