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 would go selfhosted and use a mai-in-a-box solution. Easy to setup, handles all the spam DNS settings etc and if you put it on an ip segment that is generally spammer-free, then you should have a fantastic solution (I habe used it myself for many years).
