I've been self-hosting for about 15 years now, and the only deliverability problems I've had in the past were with ISPs. I have no problem sending to Gmail, Outlook, Yahoo, and so on, or any business who hosts their own E-mail. Very occasionally, I get bounces from people who still get their E-mail through their ISP, like from AT&T or something. But I just go through the ISP's opaque process and deliverability goes back to normal.

Same here, 10 years self hosting. I've heard this claim a lot but I've never actually seen it, or seen evidence of it.

The worst I've ever had was gmail refusing to accept a ~50MB zip file as an attachment. And you know what? I'm not even mad about that one, that's totally fair.
