Hello @gdeliv,
We understand that you're having trouble with emails on the block-list. Don't worry we can point you in the right direction.
The reason the emails could be on the block-list, could be related to spam. You need to contact the postmaster abuse team to get help with getting this resolved. You're going to email the block list group.

Hello @gdeliv
Thanks for responding. If you've already emailed the postmaster, the best thing to do at this point is wait for their response regarding the blocked IP addresses.
Let us know if we can help you with anything else.
