I think a focus on transactional email would be more rewarding, as landing in spam doesn't really matter(just tell the user to check their spam folder).

Currently the best I have found is Postal.io, but its not really light.

This problem is solvable without a web interface: https://manpages.ubuntu.com/manpages/bionic/man5/dot-qmail.5...

How many people understand that man page, and how many people understand a web interface? I think it’s a clear winner.

I hate to be an elitist jerk, but if you can't understand a man page describing a single file format then maybe running an email service is something best outsourced.

Having been a part-time postmaster for more than a decade by now, I fully agree, and would even go further: Ingress spam is pretty much a solved problem if you play your cards right. ChatGPT et al. might change that again - but the mechanisms you can deploy today are very effective against the current UBE landscape. The _real_ problem is reliably getting your 100% legit mail into your consenting recipients' inboxes.

Well, ChatGPT could write a mail server too, so what are we even trying to achieve any more? Just let ChatGPT send emails to itself, using mail server and client software that it wrote itself, and the rest of us don't have any need to handle email ever again.

I believe what the parent meant was that SPAM blocking relies heavily on keywords, and strings. With the advent of chat gpt we go beyond a/b testing and push it to into the every infinite way of someone conning you to click on something through email.

If I want to send unlimited emails from my domain (not 500 max or 2000 per day) and I don't want to worry about hacks AND don't want to pay for overages, simple shared hosting is the (cheapest) way!?

It might be cheap but depending on the reputation of the hoster your e-mails will be hit or miss.

> All passwords are by default stored as salted SHA512 hash (5000 rounds). Attackers will have hard time to crack your passwords. SHA512 isn't a good choice for this, because it's optimized for fast low-memory computation. Why not use bcrypt or argon2, which are industry-accepted best practices for password hashing?

This is why I configured fail2ban with my own poste deployment.

Does not run on anything other than x64. Otherwise it's perfect.

If you want to host email on your raspberry at home, your main issue is usually that your IP will be in a known „dial-up“ IP range, that is blocked by all major email providers. And most home internet providers block port 25 too. And you need a fixed IP, it’s a nightmare if your mail server‘s ip ever changes.

This is also a problem for ARM servers. Oracle's free tier is quite generous, especially if you use their free ARM offering (4 * 1 core with 6GB of RAM, no time limit on the free offering), but you can't run Mailcow on it.

This has been flagged on Github and the dev's response was "well, don't run anything important on a free server" and that was basically the end of that. I was pretty disappointed with that, but on the other hand there's nothing that prevents you from building the images yourself on ARM.

Dovecot, Roundcube, ClamAV, Rspamd are all battle-tested and reasonable choices, but the choice of Haraka, a Node.js-based SMTP server, feels dubious. Why not exim or something similarly solid and well-understood?

We accept a substantial volume of mail using haraka. It's not perfect but it's certainly sufficient.

Have you tried Emailengine?

Any solution for CalDAV?

MailCow has CalDAV/CardDAV/ActiveSync support. They leverage Nextcloud for DAV support; you could theoretically set up a minimal Nextcloud setup to get *DAV support into this but you'll have to do it manually (and for some platforms you may need to add and configure an extra reverse proxy).
