1. I want import all my existing contact from Zoho Mail to Zoho CRM Leads/Contacts.

2. After importing is done. From next time whenever i send an email from Zoho Mail, it will check that the email is in CRM or not. If not then it that it create new Lead/Contact and i can see the email from the Leads/Contacts module. If it is alreday in the CRM, then i can see the all email including last email i sent to him/her from my Leads/Contacts module.

If these two are possible please help me to know procedure.
