Thank you all for this input/discussion, it's very interesting. In my
case, the relevant blacklists were:
UCEPROTECTL2
UCEPROTECTL3
Which are both classified as "low severity", but I have been having
problems even with being blacklisted on "low severity" lists. As
mentioned, it's being monitored now..
I do wonder, at what point is being blacklisted considered a
business-level "attack" or malicious activity against a small or medium
business? It seems anti-competitive to me.

We were told that entire IP subnet were blacklisted and you are
right: some subnet aren't blacklisted - for now..... by Google and
other email providers. In that respect, OVH seems to have a bad
reputation on email providers.
Yes, OVH generally has a bad reputation, not because OVH is bad, but
because anyone can set up a VPS and they don't filter SMTP.
I was assigned my IP while I was still running Roaring Penguin and I
knew my way around the various postmaster tools from Google, MSFT et
al. and did my best to make sure they would not block my IP.
