Interesting how for a (junior) dinosaur, like me, this was never a problem: I still run my mail, web, nextcloud, xmpp, forgejo, etc server on a former thin client under a cupboard. With a symmetrical fiber 1G connection it's been surprisingly reliable.
FAQ:
Yes, you can run self hosted mail.
Yes, it's complex.
No, it's not hard, but it takes time, as it is complex - if you want to understand it. If not, go for something like https://maddy.email/
Yes, I have a fixed IP address with a reverse DNS entry configured.
My ISP is zen.co.uk.
Yes, I have reverse DNS, DKIM, DMARC, SPF, even mta-sts.
No, I'm not switching from XMPP to Matrix - it's too server heavy, XMPP is more client oriented, which is my preference.
I know about the UK's online safecty act, I used https://onlinesafetyact.co.uk/ra_my_self_hosted_single_user_... as a template to create mine. I think the act itself is basically useless and just paperwork, but something along it's ideas is actually needed.
I block many AI crawlers from accessing code and photos, as eg. Claude is so aggressive that it's code crawlers makes my system sluggish, and I have no will to let anyone use my photos beyond printing them for their wall as decoration.
