Receiving email on iMac but not on iPhone. WILL ANYONE AT ZOHO HELP ME OUT!!!!!

Receiving email on iMac but not on iPhone. WILL ANYONE AT ZOHO HELP ME OUT!!!!!

I performed a backup with my old iPhone and restored to a new iPhone.  I NOW cannot receive or send emails on my new iPhone.  I re-entered my  Zoho  password for incoming pop.zoho.com mail server. When Mail tries to get mail it says it is the wrong password.  I'm still receiving email from Zoho on my iMac and Macbook Pro.  WHAT HAS GONE WRONG????
