@luis I specifically do not host email even at hetzner because there is just no way to guarantee any delivery if you're not hotmail/gmail/whatever, I just use different things. I don't think it would be much harder to host email at home, you just have to make sure you have a static IP because otherwise places like spamhaus will hate you because your DKIM/SPF records constantly stop/statr matching and your IP reputation score doesn't carry over
