Nice. Curious if they will also let Mythos and related LLM's also take a pass at it.

I really like running rust infra projects, and have been using stalwart for a long time. Its been excellent for self hosting email on a small hetzner instance. Highly recommended, and happy to see the rare 1.x release in the rust ecosystem. Wrote a bit about my experiences here: https://lindfors.no/blog/self-hosted-newsletter/

Have you had any issues with deliverability? Whenever I consider self-hosting email I think about the number of comments I've seen on HN saying don't.
efields · 2026-10-26 17:26:58 UTC
Same. I've been a fastmail user for years and JMAP is a must-have for me now. But infra is so much easier to manage than it used to be, and I see projects like this and I'm thinking it could just be my own affordable box in the cloud now (that I could use for other servers as well).

Whenever your email doesn't get delivered, you just resend it from your Gmail account. Receiving always works.
Youden · 2026-10-26 17:46:24 UTC
I've been self-hosting my email for years. Something that wasn't obvious to me in the beginning is that you can separate sending and receiving: host the receiving yourself and use a service for sending (e.g. Mailchimp, Sendgrid etc.). That can address many concerns.
I did that in the beginning but later set up my own relay hosted at Hetzner. I could do it on my receiving server (a PC in my house) but I don't have a static IP and IP reputation is a big deal in email deliverability.
I do very occasionally get sent to spam but it's fairly rare and I'm not sure my free Gmail account was any better.

I've also been self hosting for a couple decades, and I've taken this approach a step further. I self-deliver to most destinations, but for a while there was one destination (a regional ISP's mail server) that would not accept my emails. My solution was to route _only_ emails for that destination through MailGun. The volume was so low that I stayed within Mailgun's free tier.
BadBadJellyBean · 2026-10-26 18:13:12 UTC
Even a custom domain can be pain. I have an xyz domain and my mails usually land in the spam folder when I send from it. If you don't have enough volume you might have trouble as well.

Running a stalwart mail server since a few months for all my personal mails. I have auto dns configured and let stalwart handle all the dns stuff. Never had any issues. Last thing I needed to fix for perfect spam recognition: Switching from systemd resolve to unbound for dns resolution, which enables spamhouse & co. spam checking in stalwart. Before I had quit a few false-positives and false negatives. Switching to unbound fixed this.

I just wish there would be more pure JMAP email clients. But maybe soon!
From their website:
"Webmail for Stalwart Mail Server.
Bulwark puts mail, calendar, contacts and files in one browser client that talks JMAP to your own server."
nicce · 2026-10-27 10:45:21 UTC
Thanks. I am already using this, it seems to be the best so far. But I feel something is still missing from there by the usability aspect. It also uses NextJS which I don't know what to think about...

Disclosure: I build Keenrig, a self-hosted app platform, and I'm considering packaging Stalwart. For people running it: what should a one-click install get right (auto-DNS, cert handling, backups of the data dir) so it doesn't feel worse than a manual setup
This looks great. Quite new one, hopefully will be maintained.
snapplebobapple · 2026-10-26 20:19:14 UTC
you mentioned a secrets vault in the blog post. Is there something specific you like? I'm looking to eventualy move off bitwarden.
99harry · 2026-10-27 15:05:31 UTC
I also want to set up a mail server, but when setting it up, I heard that it needs to be authenticated so the mail doesn't go to spam and can be used as a service

This is an awesome add to my list of server software that runs on Windows Server. I love
when devs write for Windows Server.
Milpotel · 2026-10-26 18:20:05 UTC
Why? Is it some form of Stockholm syndrome?
lunargamma676 · 2026-10-26 17:28:18 UTC
Been running it on a small box and the thing I appreciate most is that it's one process instead of postfix plus dovecot plus rspamd glued together with my own mediocre unit files.
dalvrosa · 2026-10-26 20:23:28 UTC
Fair point, more relevant than speed tbh
0xc133 · 2026-10-26 17:49:37 UTC
Well, I know what I'm upgrading tonight. (I didn't see any mention of this in the blog post, but they also implemented batch-upload for the vandelay tool, so exporting your archive into a new Stalwart server is much faster now, too!)
eliaspro · 2026-10-26 18:19:34 UTC
Just yesterday I bought an enterprise license for my personal use because I felt like supporting a project that's doing many things just right!
Stalwart is a really impressive piece of software.
nikisweeting · 2026-10-26 19:18:49 UTC
Amazing engineering work! Bought a license just to support it as well.
Can't wait for webmail next!
rvdca · 2026-10-27 13:09:44 UTC
Couple with stalwart I have been using Bulkwark : bulwarkmail.org/
joshka · 2026-10-27 04:45:12 UTC
I really want to give this a try for a backup to my main email (hosted on fastmail), but a couple of those enterprise features are things I'd want to really try out as a solo hoster (AI Sieve and masked addresses). I can't justify paying $50/year for those though. :|

Pretty much all of that I had never heard of and many of them looked decent so I figured I would share.
It already has stalwart 1.0.0 support ...
