That would be an interesting research project. The domains getting most spams on my servers are the ones that are old (20+ years) which I guess makes sense.
Checking the rspamd logs for the last month gives just shy of 8500 emails with what I'd consider "definitely a spam" score. There's probably another 1000-1500 sneaking under that.

Indeed. When you say get spam, do you mean pre or post-filtering?
Over the last 30 days (I don't keep them longer than that) I've received 43 spam emails which were sent to the spam folder (so I wouldn't ever see these, other than because I went and looked now for the sake of this discussion). In the same time period there was only 1 spam email which was missed by spamprobe and made it into my inbox spool.
There's a fair amount of would-be spam that gets blocked during the SMTP transaction due to things like bogus host in HELO, etc. I don't keep any stats on those, I did at one time but it was too much noise.
My email isn't secret, it should be on every spammer list I'd guess. It has been the same since the mid 90s and is all over usenet, email list archives, websites, etc and I've never made any effort to mask it.
My mx hosted with hetzner also runs rspamd. Of the 32k mails received in the last month, 40% were rejected (postfix DISCARD, so the sender sees the mail as accepted but its sent to /dev/null - this only happens to mails scored very highly as spam, or sent to a spam trap address), 10% were greylisted and 1% were delivered to the spam folder.
So I'm also receiving 10s of spam per day, but they're all delivered to my spam folder with rare errors.
With the exception of an issue delivering to AT&T recently, I haven't had any outbound deliverability problems in a few years, but then again I don't send very much mail at all - perhaps I'd have more trouble if I did but most of my mail is incoming.
The old lists may be more plausible.
Some spammer once associated 'Robin Bennett' with my email addresses at some point 20 years ago and kept reselling it. Never used that name, didn't even know Bennett was a surname. I assume they linked me up with that name to fill up empty cells in their list and make it look more plausible.
It's a good way to filter spam. The last decade almost all spam calling me 'Bennett' is from some US political group, which mostly reminds me that it will be a long time before anything GDPR-like will pass in the US..
But almost all spam goes to that old 20 year old email address I don't use. My current email addresses are much cleaner even after 10+ year of use
Not quite sure I follow? Unless you mean "only allow emails to specific email addresses you've noted down", in which case, yeah, that works but also means a lot of admin when you want to use a new one (plus there's 10+ other people who use my servers for email, not just me.)
> unless you publish your address globally?
At least one of my email addresses has been published globally since ~1995. Others since ~2000.
