Maybe there is some compelling reason to use Haraka, but I wouldn’t know, because the author doesn’t seem willing to bother actually writing a post that contains any non-trivial information.
Moreover, the title is misleading. I was hoping it would be about implementing a simple SMTP server (though 20 minutes is a little tight for that I suppose), which actually would have been interesting, unlike this article.
The last section is really precious: “What would you create with Haraka?”
Oh I dunno, a mail server? I wasn’t aware that email was such a novel and innovative technology that I needed a prompt in order to even consider the infinite possibilities.
Looking at this guys other post, it almost seems like some blog spam MTurk job.. His articles are very short and very bad. One is a summary about graphene, with all the facts lifted off wikipedia, another is about how to use a geolocating service (lemme guess, you make a GET request to their api?), and one is basically about how to create a Digital Ocean droplet..
