A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

As everyone has mentioned SPF/DKIM/DMARC is the absolute minimum. If you're going to be sending your own mail then a PTR record is absolutely required. Also get registered dnswl.org and other whitelist sites. Be prepared to spend some time tracking down why the occasional email goes to spam. Then there's the onslaught of bots and hackers constantly trying to break in.
I've used Mailu to host my own mail server, and at my work we have a standard Postfix/Dovecot setup.
My recommendation is to use Fastmail, Proton, or some other service to save you the headache.
I understand all the pitfalls and caveats, I've maintained corporate mail services (i.e. exchange/o365) but I've not self-hosted before. I know the safe and sane solution would be a paid service, but like I said I'd like to experiment. I'll look at Mailu. Thanks.
