Not sure why you said “no”, because the whole of your remaining comment simply reinforced that reputation matters, including reputation by association.
Association extends to sharing an IP allocation. It may even extend to sharing a nameserver. Gmail isn’t randomly targeting a “little guy” for the Internet Death Penalty. This isn’t arbitrary, and an entitled victim mindset isn’t going to get your email delivered.
Like I said, prefer IPv6. For now at least, bad senders don’t choose it. That’s the something you can do about it. Pro tip: most VPS services are a swamp.
Incidentally, if your server was rooted, don’t assume that this would show up in the mail logs. There are plenty other ways to use a compromised host as an open relay, including lying to your admin tools.
Ultimately, I think that if you’re unwilling or unable to run a MTA to the maximum level of reputation, then skip doing so, and use Postmark instead.
