I absolutely agree that all VPS and server providers should do their best to deal with UCE, malware, bots and related mischief. I would add that they should make some effort to reach out to RBL's and RSL's to delist their address ranges. It would be up to a number of their customers to push for such changes before they would likely prioritize it.

I would even go as far as to suggest that both they and their customers should have aliases on all domains for spam@, uce@, postmaster@, abuse@, malware@ and security@ that route to a distribution list or mailbox that the domain holder responds to that same day. Back in the day, that was a requirement to varying degrees to sign up for any of the big email campaign providers.

Every domain holder should also have a proper DNS dmarc rule with a reporting email address listed. Example using ycombinator.com [1]

  [1] dig +short _dmarc.ycombinator.com txt

  "v=DMARC1; p=none; sp=none; rua=mailto:[e-mail],mailto:[e-mail]; aspf=r; pct=100"
