As of approx. 8 am EST today, I'm not able to forward email due to this reason:

Mail forward failure - Your IP Address 136.143.188.73 is blacklisted for spamming 

The IP address is a ZOHO mail address. Mail forwarding was disablled due to repeat mail forward failures. I tried re-enabling it, but still get mail forward failure notice. 

Anyone else having this issue/any idea when it will be resolved?

Thanks!
