Hi guys, just sharing a frustrating experience I had on gmail couple of days ago. It might be helpful for somebody:
Default, the tool chain mutt + ssmtp + gmail does *not* remove the Bcc headers! As long as you don't say set write_bcc=no in your .muttrc explicitly, mutt wont remove Bcc. I wonder what can be the reasons for having this default ... cheers -- stanio_
