Auto Bcc through terminal command no longer works?
I need to auto-Bcc every email that goes out of my office. I had been using the terminal command way (via this article: https://www.lifewire.com/automatically-bcc-os-x-mail-1172861) but my emails are not being Bcc'd now. I can't remember if the break corresponded to a system update.
When I check in terminal with "defaults read com.apple.mail UserHeaders" it says:
{
Bcc = "XXX@XXX.com";
}
So I would assume that my outgoing emails should have the specified address in the Bcc field, however, when I check my sent mail through Apple mail the Bcc fields are empty. What am I doing wrong?
