This article explains how to send a Bcc copy of outgoing email in Mozilla Thunderbird to one or more addresses.
Using Bcc (Blind Carbon Copy) in Thunderbird Email
Of course, it's nice to have a copy of all outgoing email in your Sent folder, but what if you want to collect your email in another account or archive all outgoing messages separately?
In Mozilla Thunderbird you can easily send Bcc copies of all emails to any email address. These copies are invisible to other recipients and form a trail of the emails you send or act as a secondary Sent folder.
Follow these steps to automatically send a Bcc copy of all outgoing email to one or more email addresses in Mozilla Thunderbird.
