send to bcc

Turns out we need bcc for archiving to work, no idea why this code was there in the first place ... maybe to cover up come bug in smtp or our mail generator ...
Misread the old code as just removing the bcc, but it only removed it from the email message but kept it as recipient.
With this change email body still does not include the BCC header but the recipient, so nothing should change...
