I see that in 2004, a Wiki request was posted:
"2004-10-25 - Auto-BCC option
There should be an option to automatically add the sender name to the "Bcc:" header line. Note that this option is different from (and should be independent of) automatically filing a copy of the message in the "Sent" folder."
I always want to Bcc myself so that the message is available to my POP-account-based e-mail clients (eg, Eudora). It would be very helpful if there were an option that allowed the account holder to enable the Bcc field being pre-completed with the configured e-mail address.
Thank you for your time and efforts.
