Thanks.
Nice add-on, which can save from the unpleasant situations.

But, I've found that it doesn't work together with "Secure Addressing" add-on - https://addons.mozilla.org/en-US/thunderbird/addon/secure-addressing
When it is enabled, the addresses are not changed to "Bcc" as they should.

Could it be possible to make them works together?

Thanks.

Thanks for your kind words. I am not familiar with the Secure Addressing addon but from an initial reading, I can see how the two might conflict. I would guess that things are similar to the conflict with the Send Later addon. I do not think it will be possible to make them work together. Sorry.
