Need to modify a new cpanel exim mail filter

Hi,
I am modifying a new exim mail filter as per below, all works well but.

1. wondering how to log the output to logfile /var/log/filter.log which has been created with permission 0644?

2. How would I just fail the message and not send a reply back to the spammer?

3. is there a $header_to option to stop mail sent to a specific addresses

Thanks in advance.

/etc/cpanel_exim_system_filter_new


# Filters all incoming an outgoing mail logfile /var/log/filter.log 0644
# reject spam based on email body
# logfile /var/log/filter.log 0644 

if
    $message_body contains "Good Day" or
    $message_body contains "Hello PayPal" or
    $message_body contains "Dear valued PayPal" or
    $message_body contains "forward to your positive reply"
then
    fail text "This message has been rejected because it looks like you are spamming us."
endif

if
    $header_from contains "rezult" or 
    $header_from contains "secret"  
then
    fail text "Your email has been rejected because it looks like you are spamming us."
endif

Thanks for you help Arnold, much appreciated.

The below code now works except for the logwrite, how do I make sure make sure that the exim user is the owner of the file.

Do I specify the logfile /var/log/filter.log 0644 at the top of the code or do I have to code it just above every logwrite command?

# Filters all incoming an outgoing mail logfile /var/log/filter.log 0644
# reject spam based on email body
    logfile /var/log/filter.log 0644 

if
    $message_body contains "Good Day" or
    $message_body contains "Hello PayPal" or
    $message_body contains "Dear valued PayPal" or
    $message_body contains "forward to your positive reply"
then
    logwrite "$tod_log $message_id processed"
    seen finish
#   fail text "This message has been rejected because it looks like you are spamming us."
endif
