Is anyone else re-thinking not hosting their own email server? (old.reddit.com)

For as long as I can remember I think there has been a fairly solid consensus that it's not worth it to host our own email. It's so much better and free to just let the cloud providers do it. Well, the whole AI race has me rethinking that idea lately. I recently saw a video about some setting buried in Gmail that is on by default that allows Gemini access to our emails. I'm sure Microsoft is doing similar. I also have zero faith that even if I stay on top of turning these kinds of things off that the likes of big tech will actually honor our wishes and keep our data off limits for AI.

So, am I the only one thinking about going down the forbidden path of hosting my own email server?

I do. There are now projects giving you all the required tools in a single easy package. I use stalwart mail server as it includes all the relevant functions that I would have to host separately with other solutions. (CalDAV, CardDAV, DMARC Reporting, DANE, MTA-STS, Rate Limiting, Authentication, Spam Filtering etc.). Also facilitated by having a ISP which gives me fixed IPv6 addresses for free and a fixed IPv4 for a reasonable price. I additionally host simplelogin myself for managing aliases I use for logins.

I now get a lot less spam, I think the unsolicited senders mostly concentrate on the big mailhosters.
