Filter: postie_email_reject_body

This filter is called before a reject notification email is sent and can be used to modify the message body.

At the point the filter is called there is no post created.

Parameters:

$body – a string that is the email body. The email is sent as text/plain so HTML is not supported.
$postemail – an array that represents the parsed email. See filter: postie_post_pre for more details.

add_filter('postie_email_reject_body', 'my_postie_email_reject_body', 10, 2);

function my_postie_email_reject_body($body, $postemail) {
 return $body . "\nDieser Beitrag wurde abgelehnt";
}
