Understanding Zoho Mail & Zoho Workplace Email Authentication

Zoho Mail uses "include:zoho.com" and a 2048-bit DKIM selector key configured in Zoho Mail Admin Console.

When Zoho Mail & Zoho Workplace delivers outbound emails on your behalf, recipient mail transfer agents (MTAs) at Google, Yahoo, Microsoft, and corporate mail gateways inspect the sender identity. Without a published SPF record explicitly permitting Zoho Mail & Zoho Workplace's IP ranges, these emails trigger SPF Softfail (~all) or Hardfail (-all), severely degrading domain reputation and inbox placement.
