Reason for EMAIL going into SPAM

Reason for EMAIL going into SPAM

Hi,

I believe due to the recent mail attacks, certain Zoho Servers have been blacklisted by Spam Filtering Agencies.

All mails from our domain, are being sent to SPAM because the Zoho Server (74.201.84.163) is blacklisted in Lashback IPv4 abuse database. Below is the screenshot, I request Zoho to remove this blacklisting, as most email providers use this data for Spam Assassin Tests.
