How to stop Inbound mails creating a case for Email Delivery Failure Notifications?

Hi,

I have a gmail mailbox setup as Inbound Group Mailbox in Sugar , its setup to create Cases automatically. I have a problem of cases being created for bounced back emails such as the Email Delivery Failure notification emails, which we don't want to, does anyone have any suggestions/ answers based on a similar experience? Please let me know.

Note: The SMTP used for outgoing emails from sugar uses Amazon SES(Simple Email Service) 

Regards,
Vijay
