Question : How to know that Email which i have sent to some person has received it or not ?

Dear Expert,

I like to ask
Is there any method to know that the email which i have sent to some person has received it? If he deletes the mail willingly and says that he has not received the mail then how can i know that he had received the mail... Is there is any log of downloaded or received mails on ISP's mailservers if yes, is is possible to get that log....

Thanx
Sher

I would expect ISp data to be confidential, however if you set the received/read recipt requests then as long as their mail system supports it, (and in some cases they can elect not to send the receipts) you might get some indication.

Options: Request Delivery/Read receipts.
