Steps to reproduce:

I set up a default Bcc: address in Account Settings > [Account} > Copies & Folders > Bcc these email addresses:

I click on "Accept invitation" in the invitation email.

Actual results:

The invitation acceptance message is not only sent to the person sending the invitation, but also to the Bcc: address.

Expected results:

The acceptance message should only sent to the person inviting my, but not to the Bcc: address. This can be a possible security leak. On a technical side, it is not even logical to send it to anybody else than the host and the invitees.

While I'm surprised that "works", that is what it's supposed to do. It can't be a privacy leak that Thunderbird sent a mail to the bcc you said it should send to.

Please, let's not get us distracted by a discussion, if this is a privacy leak or not (this might be a matter of definition).

May I explain my scenario?

I work for a company where all relevant emails are collected in what we call a "sales inbox". I tend to forget to include this mailbox address in the Bcc: field, so I set it up in "Account Settings > [Account} > Copies & Folders > Bcc these email addresses:" as described. If the email should not go into the sales inbox, I simply delete the address from the Bcc: field.

When I receive an invitation and accept it, this acceptance mail is sent to the sales inbox. I don't have any control, if it is sent or not. I don't want to send all accepted invitations to the sales inbox where everybody can read it.

Since I cannot delete the Bcc: from the acceptance mail, I considered in a privacy leak. Perhaps there is a better word for it?

Magnus, it begins to dawn at me, why you think this is not a privacy leak: You believe, that because I set a default Bcc: address, I must like to have all emails bcc'ed to this address!

I use the default Bcc: address in a different way: For me it is just a reminder to bcc my email to this address. This address is my company's common mailbox. I delete this address, if it not appropriate to send my emails there. I do not bcc all my emails to this address (and definitely do not want my accepted invitation end up at this address). So not being able to control the Bcc: is a security leak for me.

It might be worth checking, if the invitation is also cc'ed to default Cc: addresses ...
