I need a read receipt for the "to" email and not from others that may be cc'd
or bcc'd on the message. Can we get this specific and how?
Not possible when using SMTP as the mail protocol. Your e-mail client
will compose an aggregate list of recipients from the To, Cc, and Bcc
fields in its UI. That aggregate list is used by the e-mail client to
issue a RCPT-TO command to the mail server. For N total recipients, N
RCPT-TO commands are sent. The e-mail client then follows with 1 DATA
command that contains your message. So for N recipients, N RCPT-TO
commands are sent followed by 1 DATA command. The same e-mail gets sent
to every recipient.
If you want to send a different e-mail to some recipients then you have
to send separate e-mails.
