Blocking known spam at data center before hitting linodes

what defines spam though? different customers might want to do different things: you might just drop it, i might absorb it to do analysis on, etc.

IMO data centers shouldn't be messing with data, just passing it.

I'd think the sheer number of rules needed would also put a heavy load on the core routers (or host machines, if implemented there), too,

My sentiments exactly.

> why doesn't known spam get blocked
I don't think there is such thing as "known span".

Actually, I may very well close my accounts if such scheme were implemented lest I would miss some so-called "known spam" messages.

I agree. One of the main reasons I started my linode several years ago was I got sick and tired of ISPs messing with my email. I'll make my own decisions, thank you very much.

Agreed, I'll do it myself. My current spam-detection is far and away better than anything I've seen from an ISP, because I can custom train the bayesian filter rules and set my whitelist and not have to rely so much on blacklists, which is a good thing since they can result in a lot of false positives.
