Figure I’d ask here, but I’m looking to set something up for email in the future, I’m looking into custom domains so that if something happens with one email account, then I have more security in mind to pick up from there as opposed to being screwed.
I know that fully self hosting email full stop is usually not recommended, so I’m up for any advice anyone has on that end.
I use Mailcow myself and as long as you follow all the necessary anti-spam steps (DKIM/DMARC/SPF/etc.), it seems to work just fine.
If you’re not into all that, I would definitely recommend Proton’s hosted option. Other hosted options are also just fine for most people (even Google and Microsoft will provide you with affordable and reliable email hosting) but those are generally run by Big Tech™. On the other hand, supporting the little guy is nice and all but it also leaves you open to hacks and business continuity risks if the hosting market ever takes a turn for the worse.
