These IPs are some of Mailjets IP adresses that I have managed to figure out.

My question is what is Mailjet doing to remove these listings ASAP?

It's true that most mail providers doesn't rely on these blacklists, but some of them do... and that's enough...
If we ha one important, transactional e-mail that should have been delivered...
Especially since you keep on listing these blocks "due to blacklists" as soft bounces.
At least the should be listed as "Hard Bounces" IMO...
