Good answer! I get tired of the self hosted email FUD. Sure there’s more to it than “docker up” but it’s not that hard and it’s thoroughly documented at this point. So many tutorials.
Comment on Email for self hosted services? (Not personal email)

I’m not too concerned, for example, if they have to check their spam folders. As long as the email still lands.
In that case, it really isn’t that much of a hassle. A basic mail system isn’t that complicated to set up (just make sure you have proper authentication and such, don’t host an open proxy!). I actually did this not too long ago, using maddy, which unlike the traditional postfix+dovecot setup (which I had also been looking into) means you don’t even have to host separate services for SMTP and IMAP, and it also automates most additional things that are necessary nowadays for you, like TLS, DKIM, DMARC, and so on. Not quite everything though, there’s still stuff needed to do manually, mostly to set the SPF and DMARC records in the DNS, but it’s been working really well so far.
And really, the only mail provider you have to worry about for putting your mails into spam is gmail. They’re the worst. (maybe microsoft-hosted outlook too, but I haven’t encountered anyone using that)

I can hardly blame Google for this. My spam to legit mail ratio is over 9000.

The big problem you’ll run into is that it’s very likely outgoing connections to port 25 is blocked. In my experience it’s very uncommon that residential ISPs allow it, and even most VPS providers will block it unless you request access. So you’ll most likely need some form of relay anyway, and at that point you may as well send directly to the relay.
Port 25 being blocked on residential connections is still a thing, but it’s much less of a thing than it used to be.
I’ve never had an issue just using the submission port when the default smtp port was blocked :D

Some hosts block it by default, but if you ask, they’ll open it up no problem.

On residential connections, that’s probably the case, yes. I’m hosting it on a VPS though and have had no problems with blocked ports so far. I imagine it depends on the provider?

To be honest I haven’t done that deep search into how common it is for VPS providers to block port 25, but in the cases it has been relevant for me it has required at least raising a request and for instance for Hetzner being a customer for at least one month. I’ve figured that it’s a good thing and if a VPS provider has no restrictions at all their IP ranges are much more likely to have bad reputation and blocklist issues.
