Not OP, but yes. For personal use, you don't have enough traffic to establish reputation, so you get constantly blocked regardless of DKIM/DMARC/SPF/rDNS. Receiving mail is reliable though, so you can do that yourself and outsource just sending to things like Amazon SES or SMTP relays.
Depending on your mail flow, there's SendGrid and other options at a pretty reasonable cost to handle delivery concerns. I have one server set for sendgrid and another I've got setup for direct delivery... the only issue I've had sending from my own is to Outlook.com servers (not o365 or hotmail though). With DMARC/SPF, etc, gmail has been okay as well.

Been selfhosting personal low traffic email since the 1990's, I don't have that problem.
Me too, since 2016. I had issues with Microsoft, but it has been otherwise flawless.
