We're looking to move from faxing our purchase orders to using email by an automated process. We need a way to verify that the email was delivered and read by the person we sent it to. I brought up that not all companies provided NDRs and that not all email systems support delivery and read receipts, yet I am at a loss on a solution to this problem. With faxes there is constant handshaking between the transmit and receive. If there are too many errors then a failure is declared. We're looking to provide the same type of reliability for email. Yes, I know that email is considered a "best effort" service, but looking to see if anyone has any ideas on matter it a "better best effort" service.
Emails would probably be sent from a HP-UX server into an Exchange 2003 (soon to be 2007) environment. Paul
