I've self-hosted my email for years, and for the past 5 or so have had a stable IP address. I've got SPF records, but am missing DKIM.
I've had no problems, but just recently I had two separate emails be ignored by GMail users. Some followup communication suggests to me the mails were never seen, but I am unable to find out if they ended up in the spam folder or not. (At least one other GMail user did receive a recent mail from me.)
That has shaken my confidence in my email setup, which has run without issue for many years now.
And I don't have any end-to-end tests, other than seeing people reply to my emails. I occasionally check my domain on various blacklist checkers.
