Ugh. Docker only. So again, people are basically rejecting any engagement with the [Net|Open|Free|Dragonfly]BSD world.

iRedMail has exactly the same components, and from what I can see almost exactly the same flow logic, except its available on BSD platforms as well as linux.

Agreed the real problem is getting other servers to accept your mails.

While I can understand the paranoia, bottom line is that the number of domains that can successfully send mails is now seriously limited to a few big players who now have a virtual monopoly on emails. Which is not really good in my opinion...

Offtopic, but have people had any success maintaining a personal email domain as forwarding to the major email providers?

I have a vanity domain, and used to be able to use GMail to send email as that domain [1], and forward received mail from that domain back to GMail.

But with SPF, DKIM, and DMARC (or something), this has broken and such received email gets marked as spam and/or phishing.

I don't know how to fix the forwarding/receiving flow [2], because GMail will see the message coming from an arbitrary source, but being forwarded by an intermediate (my hosting provider's forwarding email server) which will fail its integrity checks.

I have not been able to understand how to solve this. Clearly, forwarding servers aren't a well-regarded use-case in this new era of verified email flow.

Also, I'm not just talking about GMail. I used to do forwarding for my family who used a variety of providers, so I can't just switch to GMail (via Google Domains) for my entire domain.

[1] GMail still offers that feature, under Settings->Accounts and Import->"Send mail as"

[2] the sending flow is easy: just add gmail's SPF to my own domain's

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.

It is usually not the same people who run it and who create users. You don’t want to bother the admin every time you add a new email address.

But an admin UI is more than just for creating mailboxes. It can also manage quotas, the spam filter, provide setup instructions for the end users, …

ARC is what you need, it a similar signing as DKIM, but resigns a message.

I used to use forwardemail.net for this and recently switched to cloudflare since I already use it for dns and domain registration. Seems to work fine. I use the same flow as you for outgoing mail in gmail

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?

That's the goal, to avoid things as "solid" as exim.

I hosted my own mail for some time and got into trouble with the school of my kids because they did not receive my reply to their mail. I self hosted because I wanted to prefer not to be part of the huge o365/Gmail/iCloud monocultures. Last year I moved my mail to an old fashioned shared webhosting account at Hetzner. Very happy with it!

> Last year I moved my mail to an old fashioned shared webhosting account at Hetzner. Very happy with it! How exactly is that solving the problem? If anyone does something remotely spammy from that ip, your mails are spam again too. And you probably got lucky that the ip you're sitting on was warm and trusted to begin with. You didn't really find a solution, the problem simply hasn't occurred yet for you or you are n…

From my experience shared web hosting accounts have the worst trust. You get the IP range of a public cloud provider, but you also share it with random people, that will send spam at some point.

So either get a package at some of those smaller providers with a dedicated IP, or go to one of the big providers (Google, Microsoft) and use their highly trusted IPs, that everybody whitelists by default.

I have for many years BUT you have to pay Google to make it work. It used to be free but I guess it was abused too much for spam. Now you have to pay for Google workspace and it should work.

You can't forward email to Gmail - they'll blame your server for forwarded spam regardless of everything else being correctly set up. This is true to an extent for other providers, too.

The simplest solution is to set up IMAP on your mail server and have remote mail accounts fetch from it. Most email providers can be configured to fetch via IMAP.
