OpenSMTPD VS Haraka

Any MTA will do, including OpenSMTPD, Postifix, Exim, Sendmail, qmail.

OpenSMTPD

opensmtpd Like: Reasonable sized, reasonably easy to configure Dislike: Easy to shoot yourself in the foot, DKIM setup is a p.i.t.a.

Sounds like OpenSMTPd https://www.opensmtpd.org/ in that its a rewrite of older confusing SMTP servers.

Any constructive suggestions about what beginners should refer to? Is there anything better than the FAQ? (And, any thoughts about a guide for smtpd? I know this is a rather different question, but I'd love to find something beyond just the manual pages at www.opensmtpd.org, )

postale.io has an MX record that points to mail.postale.io, which resolves to an AWS IP address (probably an EC2 instance) and has Haraka listening on port 25 (if its SMTP banner can be believed)

I found that Zerodha uses Haraka and Karan–their DevOps guy, mentioned it is easy-setup and performant.

The next time this happens i'll move to a self hosted solution, like haraka or anonaddy

Haraka Like: Simple to hook into the processing pipeline Dislike: Node.js and had some issues with stability when I last tried it

Having another SMTP as a choice is cool but not as fun as something that is way more configurable (ex. Haraka), or API driven (a la Postal).

Look at Haraka: http://haraka.github.io/

For the record, I'm using dovecot (https://www.dovecot.org/) for IMAP and Haraka (https://haraka.github.io/) for SMTP.

I run my own mail servers for small projects, though for my main email I've actually switched to ProtonMail.

It's never been easier to self host your email with projects like the following around:

- https://foxcpp.dev/maddy/

- https://github.com/albertito/chasquid

- https://github.com/haraka/haraka

Of course the usual dovecot + postfix setup is great for learning even if a bit complicated.

Haraka (https://haraka.github.io/) is a plugin-based mailserver written in JavaScript. I've messed with postfix before but found Haraka easier because instead of arcane configuration files I can just read, copy, and tweak a plugin to suit my needs. Policies for receiving, storing, forwarding, and ignoring mail can be arbitrarily complex.
