All of a sudden Bcc stopped working; it defaults to TO and displays all email addresses. I have tried downloading the Bcc Add On and making Bcc my default but it still reverts to TO when the emails get sent and displays all email addresses when received by the recipients. This is distressing. Please help. Thank you.

Are you saying it changes to To: in your copy in the Sent folder? Or just that the recipients see it this way?

It may be that your SMTP server is doing this, which would put it beyond Thunderbird's control.

After Thunderbird's recent update the problem appears to be solved. Hopefully, it will continue to stay that way.
