We are using Zoho to receive automated system alerts from our data center which we also have forwarded to our on-call engineers' personal addresses which rotate each week.
Now we are receiving these notifications from zoho and emails are being blocked.
Is there anything from ZOHO that can be done to allow these through? This never occurred with our previous email hosting provider which forwarded the exact same emails daily to the same addresses.
Something with the headers of the forward and/or 74.201.154.111 being on a blacklist seems to be a factor.
