It's never been easier to self-host, but it feels like, in general, when faced with "I want to do X with a computer," people are more and more reaching for paid, hosted services rather than DIY anymore.
1. Deliverability: "the email mafia will flag your emails as spam"
2. Complexity: "configuring and maintaining a mail stack is a technical nightmare".
3. Network blocks: VPS providers and residential ISPs frequently block outbound mail ports (like port 25) entirely or in their terms of use.
I decided we should try self-hosting because some issues with their reliability cost us very expensive problems. The experience was frustrating anyway, as the weird restrictions on providers caused our setup to be quite bad on some regards -- most notably being forced to use the provider UI to manage some things, which took time and is a non-transferable useless skill, not having users for things that should have had one, etc.
MailCow made the technical setup trivial, blowing objection #2 out. For #3, we could not rely on stable electricity/internet, so we just spun it up on a reliable VPS provider after a small research. As for the biggest fear, the IP reputation and deliverability mafia (#1), it is easily solved by routing outbound mail through a simple SMTP relay like SMTP2GO. You pay based purely on sending volume rather than a flat service fee, and their free tier completely covers small setups. And how much time did it take? Less than half a day, before AI could do everything for you.
Most paid services charge absurd per-user or per-domain fees for basic features that do not cost them anything. After 2 years of bad service on paid providers followed by 2 years of flawless self-hosting, there is absolutely no going back.
The cost of something like AWS SES or Postmark is so low as to make it almost not worth it, but it worked; not that I'd trust "real" email to it - but I was surprised that Wordpress setup emails were getting through with little config.
I self hosted my email domains for 15+ years. Finally got fed up with the constant trickle of the maintenance and got a service for everything.
Not quite happy with that as they don't even do SRS (implying they do), but i guess I'll just migrate elsewhere.
The upside is I've got more time for myself and have less CVEs to worry about.
Self hosted apps migration in progress; I guess I'll leave media, book and file server only, off the internet, and that's it.
Even if you don't actively monitor your server and only notice there's a problem after three days of not getting any mail, odds are you'll still receive most of them after fixing the issue.
I've been very happy with it. I have a perfectly normal email service, over which I have full control. MailInABox handles all the necessary DKIM etc. I had minor hassles, when I first started, with sending to google and microsoft, but these were reasonably easily managed by following microsoft's advice. (And I have a good ISP.)
The only hassle is that, because MailInABox uses greylisting, initial account-validation emails are sometimes delayed. But because I have control of the service, I can whitelist anything important :)
Also, my understanding is that Google, Outlook and other major email services have been implementing as many roadblocks for self-hosted setups as possible to the point where it's a constant battle and difficult to keep up with.
other self hosting? sure.
Email receivers (be it Gmail or your local council) don't differentiate if you're self hosting or a business. So long as small businesses can manage (who have like one part-time sysadmin that also manages a ton of other IT stuff; email doesn't take much of their time), so can you. If you set up the usual suspects like SPF and DMARC, the domain is not a known spammer, and the IP not in a blocked address range, it's mostly hands-off (source: I self host my email)
If you need it to really be super reliable, yeah, you need to send through one of the big companies who have not just a dedicated sending IP address but entire ranges dedicated to email sending, as well as staff that will respond to delivery issues 24/7. Microsoft rejecting email from Google and vice versa isn't unheard of, so there aren't guarantees anywhere, but that would be your best bet. For my personal use, that extra nine of reliability isn't needed
But agreed that mass-mailing (even account registration style emails) seems a lot less reliable because of those spam filters.
all complete bullshit; they arbitrraly occasionally block to protect their moat raping privacy. e-mail is the most rewarding self-hosting capability. like anything, there is a learning curve but at the end of the day: it's easy, stable, a pleasure to host. there are solutions that ease the learning curve. after a while, all the e-mail do make it through.
i'm so happy that my communications are not indexed by these hyperscalers.
stop listening to these pussies claiming how difficult it is. they're projecting their limitations.
There's little to no incentive for providers to ever de-escalate.
At my day job, we use Gsuite. I never used it for any non-work purpose, and it wasn't publically published, so any "spam" it got was false positives. Emails I actually needed were being buried below the fold in the spam folder. It turns out there is no obvious way to 100% disable spam filtering (at the time I got the first false-positive at least) so I had to try to just allowlist things that should be left alone.
