Hi

I think the question is little vague.

What is the main purpose of establishing the relationship please?

Having said that I assume you want to capture the data of the senders and recipients based on sending item like:-

A sends email to B
B sends email to C
A sends email to D.

Then you can create a third table using everyone's telephone number.

Assuming A is 111, B is 222, C is 333 and D is 444

then the third table would like following

sender recipient

111 222
222 333
111 444

Thanks
