Plx:

 

Hello. I have a small (20ish messages/day) email server currently hosted on a VPS offshore. Can I run this from home with a static IP from Quic?

 

"Can I?" - Yes you can. "Should I?" - Mmmm?

I have run a mail server for many years and continue to do so. With Quic you can set both IPv4 and IPv6 reverse DNS, then you can do all the other things (SPF, ... as mentioned above) to improve your reputation. There is no network layer filtering of SMTP by Quic.
