fair enough -I can understand that perspective

What is my best bet? AWS? Azure?

OVH is a well known den of spam, scraper and malicious bots. This is your problem. I am sure Spamhaus has given up on the number of bots they need to block and banned the whole IP range. I know I have. You need to move to another host provider. OVH allows the rampant running of bots, so this is what they get. Total ban.

Do you have reverse DNS records set up -- this is pretty much a
requirement for running any mail server these days.

This mailing list kept getting blocked by Spamhaus when we used IPv6
address to send out mail. I have no idea what was wrong with that, but
the minute I turned off IPv6 everything went back to normal.

I remember there's an open-source mail config/blacklist checking website
tool, but I don't remember its name.
