How salesforce matches Contact to the case when an email is received in Email-To-Case

Hi Guys,

I have been working on salesforce's Email to case Functionality since December. I cant say am perfect in it , but have got a good hold as of now.

Let me just walk you through how salesforce Email-To-Case functionality works. Though , ll not brief here about setting email to case .

So, when an customer sends an email to salesforce org. Then a case is created in the salesforce.

Let say, You have a contact  with a name xyz and his email address is xyz@abc.com. So, when he ll send an email to raise a case, his case will be created and and his contact will be asscoiciatd  with this case.

And how salesforce does this, all explationaltion is given here in salesforce know;ledge article.
