Tangentially, I've been using my own domain with Gmail for years, but as of ~1y ago, it's been causing me problems. Emails sent from such custom addresses to my domain (which forwards back to my gmail) get a "This might be phishing" banner.
See, Gmail lets you configure it so that you can send emails as another address. This required a bit of verification via a DNS check, but trivial if you controlled your domain.
However, with the advent of SPF/DKIM/DMARC enforcing, this doesn't work well anymore. My main problem is that my domain is configured to forward select emails back to gmail. This breaks SPF, and I haven't yet found a way to fix this with Gmail.
I guess I need to wade through some SPF/DKIM/DMARC documentation. Google's own has not been useful.
