Zoho CRM Email Module

I use Zoho CRM for my business and I make frequent use of the mail portal from within the leads/contacts window to communicate with leads and contacts. I have two different email addresses that I use for my business but I'm able to have only one enabled at a time for Zoho CRM. If I forward the emails from the one address to the other that I have enabled on my account will those start showing up in the email portal?
