Hopefully, you can answer this related BCC question. When I send an email with BCC addresses as well as To and CC addresses and then later go to the Sent folder to review the email, the email that opens up from the Sent folder does not list the BCC addresses. This is frustrating because I need a record of all addressees. This happens when sending emails on all of my email services/companies. If I can't see and retain a record of all my addressees, I will not be able to continue using Mail. Hopefully, there is some preferences box that I forgot to check that will enable showing me the BCCs in my original email. Any ideas/recommendations?
