Our software sends emails using Exchange. Typically each email foes to multiple recipients and we just send one email with multiple "to" addresses.
We're moving to an SMTP-based email relay, where we send the email to an Exchange server, and it relays the email on. One thing we want is that each recipient should not know the recipient-list, and at the moment we plan to simply put all recipients in the email "bcc" list. But it seems like this might be a really common issue that Exchange (and other relay software) might handle in a better way.
Can anyone tell me if there is a 'right way' to do this, and any technical terms I need to know?
We prefer not to send the email multiple times from our software.
