I created an email provider called Port87 that specializes in spam prevention, phishing prevention, and organization.
You use it by giving a labeled address to all your accounts, so to Netflix, you would give something like [email protected]. Then that becomes a label in your account that you can set quick settings for like mark as read or even just block that address if you’re done with it. And if you get something claiming to be from your bank there, you know it’s phishing.
Then you can have labels that are meant for real people like [email protected], and when someone emails them for the first time it will email them back and ask them to verify they’re human.
And your bare address ([email protected]) doesn’t go through, but rather responds with a list of your “public label” addresses. So that one you can share all over the internet and you won’t get spammed.
Sounds like you have qmail at the root. I ran that with spamassassin, barracuda and some other custom rules for years. Didn't add on the auto response you have described, but really liked it back in the day.
Did I guess kinda close to what you have running?
I'd think the annoying part would be that you've forced the work to prove they are human back on the sender. Might be a good way to go though given how much spam there is.
It’s actually built on Haraka. All of the queueing is custom written so I can do things like make it a flip of a toggle whether you want push notifications, sender screening, mark as read, etc. for a label. And there’s no inbox, since the bare address is not a usable address. Every email you receive already has at least one label.
