[web2py] BCC in web2py?

[Chris]

Hello,

I've been using web2py to send mail, and one of my users alerted me
that BCCs are visible!

I'm using a gmail account, standard web2py setup, and using the
following code:

 status = mail.send(to="%s <%s>" %
(recipient['first_name'],custom_recipient or recipient['email']),
                subject=model_data['subject'],
                bcc = bcc,
                message=("This is an HTML email, please let Chris know
you can't see it.",message_html))

Any ideas?

Thanks,
Chris
