Connecting an e-mail label in Sugar CRM

Good afternoon,

I am currently to connect an e-mail account with Sugar CRM. To be specific: I want the  incoming e-mail organized under a label to be forwarded as case into SugarCRM. Does SugarCRM recognize labels in an inbox? 

I have been trying to figure out how to do this. The general mail from the mailbox is already being forwarded as case, but not the e-mail under the label in the mailbox.

We are using G-mail in the webbrowser as e-mail client. 

Thank you in advance for your answer.

Best regards,

Maike
