I have found that many RBL's block whole IP blocks owned by various vendors. I believe this is why Linode and others like Digital Ocean now block port 25 on VPSs and make you beg for them to open it. Too many spammers.
This is also a good reason to keep a VPS even if you aren't using it at the moment: it keeps the IP "clean" so that when you put it back into use, it is useful, as opposed to (possibly) some random IP that up until a month ago was spammer central.

That won't protect you from the block getting on a blacklist though.
- geocrasher 5y agoNo, it won't. But it's better than trying to send mail from an IP that a month ago was hosting phishing sites.
