Hi
I'm still a newbie.
Don't know if it helps. I've just tested this mod in class.email. This will cc or bcc addresses.
It appears that class.email is the wrapper class for outgoing emails.
$headers = array ('From' => $from,
'To' => $to,
'Cc' => "spam1@sys.co.uk",
'Subject' => $subject,
'Date'=>date('D, d M Y H O'),
'Message-ID' =>'<'.Misc:(6).''.time().'-'.$this->getEmail().'>',
'X-Mailer' =>'osTicket v 1.6',
'Content-Type' => 'text/html; charset="UTF-8"'
);
Regards
G
