Capturing outbound mail

Capturing outbound mail

We are using Zoho CRM, and the system is working great for grabbing and associating inbound mails with the right accounts or leads. Is there a way to achieve the same thing with outbound mails?  

I know that if I click on SEND MAIL while in that Zoho contact record, the outbound mail will be captured and recorded with the account. But I want to see every message sent from my standard email client get captured and stored with the contact history. 

I have tired CCing the Zohomail account on all messages, but this does not work. Does the Outlook plug-in perform this function? If so, is there any way to do the same in different SMTP email client?

Thanks much!
