Gmail pack - get actual message id?

In the gmail pack there is an option to show message id, but this is gmail’s unique identifier. Is it possible to get the actual message id that is the same for both the sender and the receiver? It should look something like this **********************mK_kVEa89_CbSTx2M3jjn-qSuWTbMxgr3YhDQ@mail.gmail.com

Thank you,

What are you trying to do with it specifically?
