sending email using "bcc" without "to" in java application

Question

I have read all the reference in stackoverflow. However, nothing matches in our goal. How can i use bcc in sendmail method in java?

Answer 1

According to the RFC for SMTP, RFC 2821 (link), it is not possible to send an email message without a To: header. (You cannot send an RCPT command without it, see section 3.3.)

Answer 2

As Dietrich mentions, that's not possible with the RFC. If the primary goal is to send to the bcc target email addresses, you could provide a dummy to email address (such as your own email address or a reply-to email), which would fulfill that technicality while still allowing you to send the email to the desired bcc targets.
