Chris, this is correct. If you pass your headers through vbmail(), vB will add your headers, among its own (from, return-path, auto-submitted, message-id, mime-version, content-type, transfer-encoding, x-priority, x-mailer). If this is unwanted, and if you want to avoid patching any native vB code, I suggest you extend the vB_Mail class from includes/class_mail.php.

Best,
Alex
