Unwanted Email's by Trackback and Pingback

Hi ,
I am using your wordpress theme for my website . But i am getting unwanted trackback emails from your theme (not sure by using your code). The emails i am receiving was not related to my website content , because my website related to Cooking recipes. I am using many plugins to make this website as per my needs . Also i am using plugin to post recipe .
I think they are emailing from that plugin which i have installed in your theme.

Kindly help me regarding this , because i am getting such emails regularly in the interval of every two days ???
