My emails are hosted in Linode. I believe there is no need to block linode outright for several reasons:
1) In the past, it was possible for spammers to automatically buy linode servers, boot them, install their spam software and start spamming. All via the linode developers API. This is no longer possible, all accounts have port 25 blocked by default and require manual intervention to get it open. 2) In the past, their abuse@ email address wasn't very... hmm responsive. But since two years ago, they provide nearly instant human support. When I email them about bad connections from their network, they are quick to respond and to kill any rogue accounts. This mailing list is the only place I have problems delivering emails. Everything else (ibm/redhat/microsoft/apple/amazon/google/etc) works fine without blocks.
