Hi:

I am receiving confirmation of an email sent by a cousin to his dad.
The strange thing is how can I receive an email confirmation when I
was not an addressee?

All three of us have different ISP's. My cousin has his email
settings to receive confirmation of receipts, but again how can I be
receiving a confirmation when he sends his dad an email and his dad
opens it? In addition, all emails that his dad sends him I get a copy
even though I am not an addressee.

This is mind boggling and I sure hope someone can tell me what needs
to be accomplished to prevent this from happening.

Thanks

Adding to the other responses:

Some rather unlikely, but possible, other causes:

- Your cousin has set your e-mail address in his Reply-To: header. Of
course this does not have to be an *intentional* setting, but someone
or something *could* have done that. This assumes that your cousin's
dad's mailer does the right thing and honors the Reply-to: header.
This cause is unlikely because this way you cousin would not likely to
receive *any* mail, because *all* mail, i.e. not only receipt
confirmations, should go to you.

- Same story as above but now for some (AFAIK (As Far As I Know))
non-standard "X-Receipts-To:" (or some such) header.
This cause is slightly less unlikely, because (if your cousin's dad's
mailer honors this header) the receipt confirmations would go to you
(as they do), but normal mail or normal replies would still go to your
cousin.

Again: This is all *unlikely*, but *possible*.
