I mean anything that is not hosted in your house. For example, dynamic dns, some type of ddos protection, off-site backups, external oauth provider, etc.

An external email host. Life is too short to deal with frustrating email issues.
I’d recommend looking again, as I think that advice is becoming dated. Greylist and DKIM make spam prevention super simple, ironically because the centralization of email towards Outlook and gmail has trained pretty much every sender to follow the rules or your email doesn’t go through. And then Greylist catches the rest, because spammers don’t come back and retry after a few minutes.
The problem isn’t incoming spam, but rather not being able to send to the larger email providers because of arbitrary spamfiltering on their side.
