A Yankee screwdriver in the right hands is faster than an electric screwdriver

What I am proposing was a setup wizard combined with a vps. To make it easy to be self-sovereign with your email.

Dead men tell no tales

I have no idea what you're talking about. I've been running email servers for over 30 years, I know what I'm talking about. Not folklore.

Running an email server for your personal email address is a completely different problem than running an email service. The IP reputation (RBL) problem is not a problem so long as you aren't running it from a dynamic address or a IP pool marked as residential internet. Abuse handling again isn't a problem as long as you aren't abusing your own server. Forwarding breakage again isn't a problem if you are running your own server and your own local root-DNS, which is trivial with bind9. There are several gotchas, such as not knowing you can't check RBLs from a public DNS like Google's public servers. But this all can be handled by a setup wizard. Again, running your own vps for your own email on your own domain is not that hard and that is what SMTP was designed for. As long as you don't do stupid things like open up your server as a global delivery service, its going to work fine.
My original comment, to use @LNVPS.net is a real option for having your own private email address.

I finally see the failure mode of spark, and that means it is very much a custodial system, no different than a cashu mint, but with worse privacy.

Jew-haters are in favor of Israelis blowing up Christian and Muslim children in Gaza and Palestine. I'm confused.

As long as you're not *actually* spamming, you aren't going to be getting flagged on the RBLs

SPF, DKIM, DMARC and SRV and TXT DNS records aren't rocket science. These could be done through a setup wizard paired with a lightning-paid vps like @LNVPS.net

You can purchase a vps for sats and run your own email server. Go federated protocols! (sarcasm)

Is anti-semite the correct ad hominem in this context?
