Have there been independent third party code and network penetration tests performed on Stalwart and what were the findings?

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/

This is an awesome add to my list of server software that runs on Windows Server. I love when devs write for Windows Server.

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.

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!)

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.

Amazing engineering work! Bought a license just to support it as well. Can't wait for webmail next!

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. :|
