hosting email from multiple domains under 1 org Zoho account

We have two different brands and a parent company.
Everyone is employee of the parent company A, but they may also be working under brand name B or C or both.
Is it possible to setup Zoho BUsiness organization in a way that user John Doe would be able to log into Zoho Business and pick up and send emails from john.doe@company A.com, john.doe@company B.com, and john.doe@company C.com?
I know it is possible to POP3 from other servers, but I would rather move everything to Zoho, instead of keeping multiple providers.
