My wordpress settings email is [email protected]. When I search my entire database for the email of [email protected], it does not exist.

Yet my registration emails are still sent from [email protected] for some reason.

The only thing I can think of is that when I look in my wp_users table, I have no user with the ID of 1. I believe this is the default admin ID. I'm not sure who did it or when, but I think the default admin was deleted a long time ago and I just made my username admin. Perhaps if wordpress doesn't find an admin email, it automatically goes to wordpress@?

I'm confused with this one.

Ok, then you can try this You can set the header, just not with a parameter. WordPress uses "hooks" and the hooks you need are 'wp_mail_from' and 'wp_mail_from_name' hooks.

Here are the hooks you might add to your theme's functions.php file to modify the "From:" header when using wp_mail() to the email address Greg j :

function yoursite_wp_mail_from($content_type) {
  return '[email protected]';
function yoursite_wp_mail_from_name($name) {
  return 'Greg j';

WordPress does not look at your admin email, it uses the made-up address, each time wp_mail() was called without a From header.

// From email and name
// If we don't have a name from the input headers
if ( !isset( $from_name ) )
    $from_name = 'WordPress';

/* If we don't have an email from the input headers default to wordpress@$sitename
 * Some hosts will block outgoing mail from this address if it doesn't exist but
 * there's no easy alternative. Defaulting to admin_email might appear to be another
 * option but some hosts may refuse to relay mail from an unknown domain. See
 * http://trac.wordpress.org/ticket/5007.

if ( !isset( $from_email ) ) {
    // Get the site domain and get rid of www.
    $sitename = strtolower( $_SERVER['SERVER_NAME'] );
    if ( substr( $sitename, 0, 4 ) == 'www.' ) {
        $sitename = substr( $sitename, 4 );

    $from_email = 'wordpress@' . $sitename;

You can filter that from address and the name: changing notification emails from WordPress <wordpress>@mydomain.net to something else

In some cases you must filter it: when your domain name is www.tld, WordPress will strip the www. and use an email address wordpress@tld.
