Hello,

We have a client utilizing one of our IP addresses and found they had been listed on several RBLs. Blocks correlated with bulk emails being sent from their mailing lists and that has since been updated. We sent an email to [email protected] to get delisted, but we only received an automated response back and find we're still being blocked a week later. Is there anyone who might be able to help us with this? Latest bounce below:

Delivery has failed to these recipients:
