Question

How can I confirm that an email address truly belongs to the person who provided it?

Answer 1

There are services like NetIBA that verifies the person to the email address. Other than that you can be who you want to be here! So I agree with one of the other answers in that reguard.

Answer 2

You can't to do that, most especially if the email addy is from 1 of the numerous free mail server. Except the mail is from a particular organisation with which the person is working with.

Answer 3

i dont think you can unless it is for an organisation where they have the persons name and organisation as part of the address
