Hi, 

We generally put a specific subject line(like "Quotation Request / XXX" ) in all of our emails which we send to the vendors. So that we can track the reply e-mails from vendors for a specific project easily. 

I would like to create a new related list(new module) in DEALS. In that module of a DEAL; I want to see all the emails that I receive from the vendors(or from anyone) with the subject line of "....XXX".

Please suggest me a way to do that.

Thank you in advance.

Regards,

Engin
