Deliver emails to Cc in smtplib code path

When using the sendmail() function with smtplib.SMTP or
smtplib.SMTP_SSL, the list of actual recipients for the email (to be
translated to RCPT commands) has to be provided as a parameter.

Update the notification script and add all Cc recipients to that
parameter.
