What would be nice is if there could be whitelists as well, or a blacklist that additionally keeps count of positive interactions.
I've had an IP for about a decade that never once sent spam, but has ended up on blacklists from time to time (hosting EICAR on a web server apparently gets your mail server banned, 15-year-old me found out). SPF nicely says that this IP is supposed to be sending email for this domain. I don't think I'm on blacklists anymore, but email still ends up in spam folders nine out of ten times. People are giving off signals that my messages aren't spam all the time (it's my personal email server).
Years of non-spam emails count for nothing whereas a single spam mail from an adjacent IP can get you on such a list. Somehow it's a bit imbalanced.
