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/
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.
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).
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!)
