Gets the list of recipients the message was successfully delivered to.
A reference to the EmailAddressCollection object which contains the list of all recipients which received the message.
The list of recipients returned by this property indicates which recipients have been accepted by SMTP servers the message was submitted to.
Note Although a particular domain's SMTP server may successfully accept the message for delivery (and the recipients of this domain will be added into SuccessfulRecipients) list), it still does not guarantee the server itself will deliver the message to the recipients. Many servers accept non-existent recipient e-mail addresses when the message is being submitted, and then send bounced message back to the sender if certain e-mail address is invalid.
