Sendmail and gnupg

Question

I am looking for a way to configure wordpress on my RHEL4 machine to send out email notifications using gnupg (sendmail).

Can anyone point me in the right direction?

Answer 1

WordPress uses it's own function wp_mail() to send out emails. Since it is a 'pluggable' function, you can override it with your own version in a WordPress plugin;

/**
 * Plugin Name: GNUPG Mail
 * Description: Send mail using GNUPG.
 */

function wp_mail($to, $subject, $message, $headers = '', $attachments = array())
{
    // use the PHP GnuPG library here to send mail.
}
