The title is showing quite a lot of ankle! OP is a proud self hoster.

I run my own email, DNS and the rest. Yes: email. I run several domains including my own company and my own vanity domain and several more for friends. I have been doing it for decades.

Goog, MS and co do follow standards and if you do too, they will be largely merciful if you keep your nose clean. I have even managed to run an email system from my home connection as a test IPv4 and 6. I'm UK based. It does seem that IP denylists do seem to be a bit brutal in the USofA, so that might explain the downer meme on self hosting email.

The future is and always will be self hosted if you give a shit.

Haha! "Showing a lot of ankle" – I've never heard that before! Thanks for reading and commenting – very cool that you've managed to successfully host email. I'm sad advertisers and spammers have turned that into essentially an unusable technology.

Definitely a proud self hoster, but the main point is really that I don't think we're going to live in a world where self-hosting is the dominant method of using internet-based apps and services. Would love to be wrong though! Maybe we'll all be self-hosting email in a few years!

Self hosting email will always be niche and frankly it was pretty niche in the noughties too.

I do find that if you carefully curate an IP address ... now that's the real problem. Most IP blacklists aggregate and generally end up roll up to cover entire AS ranges and allocations instead of actual individual perpetrators. However, if you can grab a "corporate ISP" static IP address, you are normally OK, at least in the UK.

Then you need to get a reverse DNS entry sorted out, although this only bit one of my friends recently after five years of not me not bothering. rDNS used to be rule one in anti spam. Oh well 8)

Modern (lol) email systems generally look for SSL/TLS and SPF, DKIM is nice and if you have DMARC then you are clearly a jolly good chap. Then they have a ... rule set, some of which are as old as my email management experience and some of which are down right odd (and probably based on Bayesian learning)

Anyway, email self hosting isn't impossible. Anyone who claims to be a nerd really should be able to manage it ... 8)

I don't want to live in a world where self hosting is impossible. It'll be the same one where I don't own a drill-driver and that would be bloody weird.

		I work in the email industry, so I might be a bit biased on this one, but in my experience self-hosting email has actually gotten better, or at least for the outbound part, funnily enough. But I won't go into why IP-reputation is a thing of the past, for the risk of having to write a very long post that'll be downvoted anyway. The biggest problem that I personally see with self-hosting, email in particular, is that most resources you find online are outdated, based on superstition, or simply plain wrong. There is a lot of heated debate around running email services, and many bitter comments from people who tried once and got burned. Self-hosting a personal email service, or any kind of service for that matter, isn't impossible. The internet is still based on free and open standards (the RFCs). But it is free like speech, not beer. Running your own services will cost you resources. Most of which is your time, but some may also be money (for example: ML-capable hardware, certificates, licenses, etc.). You'll have to be willing to learn, and more importantly: willing to accept that it is a lot of work to setup and maintain any self-hosted services, not just email. You have got to be willing to read through the RFCs, study the errata, read the documentation of your software, be willing to spend time in configurations, being sure you understand your settings, set up lab environments to study both ends of the service (for example: the inbound and outbound service in an email transaction). Self-hosting is a great learning experience, a fun hobby even if you enjoy such things. It'll allow you to explore all sorts of tech throughout the entire networking stack. But due to the amount of work it takes to setup and maintain, it'll never make financial sense to self-host, at least not in a professional setting. Cloud-hosted solutions, email being a good example in particular, have the benefit of scale: they are dirt-cheap and work really well. It makes zero financial sense to self-host any email service beyond personal use. Unless hosting is your core business, don't be tempted to self-host anything, focus on your actual business instead.
