Selfhosted
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.

I recently set up the whole stack (Postfix, Dovecot, OpenDKIM) on a VPS. I wanted to do it from home, but my ISP won't provide a static IP or open ports 25/465/587 for consumer customers, no exceptions.
It took me about two days to get everything working, but most of that was because I went in with very little knowledge of how email even actually works. If you're looking for a learning experience, I'd say go for it. If you just want a working email setup quickly, I wouldn't recommend it.
I haven't noticed any deliverability issues so far. Just make sure you have SPF, DKIM, DMARC, and PTR records all set correctly from the start.
Which VPS provider are you using? Many of them end up blacklisted for mail delivery due to spammers using them.
I chose one from this list: https://github.com/forwardemail/awesome-mail-server-providers?tab=readme-ov-file#vps-and-dedicated-mail-server-provider-comparison-table
