No.

There's no telling how many SMTP gateways and AV/Spam filtering boxes your message will pass through, each manufactured by one of dozens or hundreds of possible vendors, and each vendor will implement their own notification options. There's no way to know for sure what notification options have been enabled / disabled on any of the boxes your message will pass through.
