(Chilkat for Android™ API)
Getting TO / CC Email Recipients

Demonstrates how to examine the TO and CC recipients of an email.

Note: BCC recipients are generally NOT found in the email's MIME. "BCC" is a "Blind Carbon Copy", which means that the TO and CC recipients of the email should not be able to see the BCC recipients. If the BCC email addresses were found in the MIME header, then they would no longer be "blind" because nothing would prevent the other recipients from seeing the list of BCC recipients.

To understand how BCC recipients receive an email, I recommend reading this blog post: SMTP Protocol in a Nutshell. The BCC recipients are passed to the SMTP server in “RCPT TO” commands.
