Thunderbird sends email and CC: very well, just recently it will not send Bcc: of the same email.

I continue to receive this message: Sending of the message failed. The message could not be sent using Outgoing server (SMTP) smtp.mail.yahoo.com for an unknown reason. Please verify that your Outgoing server (SMTP) settings are correct and try again.
