Allowing such queries would be giving quite a bit of information to potential bad guys.
honestly don't know what is better. The majority of DNBLs can be queried publicly, and I could imagine for those who really aim hard, simply spamming some known accounts on the destination MX helps to find out if they're blocked or not. But on that I don't have enough insight to make an educated guess.

But I was primarily suggesting a test against the infra to see if the mail was bounced or accepted. If accepted, it WOULD be delivered either to the INBOX or Junk. And if bounced, that should also highlight why.
With a proper test account it's quick to find out if you're blocked or not, indeed.
The issue in my case was the radio silence after the initial ticket. I would assume the previous IP owner really did bad, or some spammy neighbours massively rate down the netblock, so probably people were not eager to follow-up - but not the nicest experience. But, not your fault personally. ;-) And it's finally fixed in the meantime.
