sending mail cc, bcc

[Alberto Vera]

Hello:

I have a library called smtplib that send email
I use these lines to use it: (from -->to)
------------------------------------
server = smtplib.SMTP(server)
server.sendmail(fromaddr, toaddrs, message)
------------------------------------

But I'd like to include some mails CC ,BCC.
(from -->to)
( |-->cc )
( |-->bcc)

Does anyone have a library to make it? (mail: from, to, cc, bcc)

Regards
