Keep the From Address on Your Own Domain
When a plugin sends email "from" a visitor's or a free webmail address, switches the From to your own domain and keeps the original address as Reply-To, so emails pass SPF and DMARC checks.
Opens WPIDE on
Code
$wpide_aligned_from = ''; // Address on your domain; empty = wordpress@yourdomain.
add_action( 'phpmailer_init', function ( $phpmailer ) use ( $wpide_aligned_from ) {
$site = preg_replace( '/^www\./', '', (string) wp_parse_url( home_url(), PHP_URL_HOST ) );
$domain = strtolower( (string) substr( strrchr( (string) $phpmailer->From, '@' ), 1 ) );
if ( '' === $site || $domain === $site || ( strlen( $domain ) > strlen( $site ) && substr( $domain, -strlen( '.' . $site ) ) === '.' . $site ) ) {
return;
}
$original = $phpmailer->From;
$name = $phpmailer->FromName;
$from = is_email( $wpide_aligned_from ) ? $wpide_aligned_from : 'wordpress@' . $site;
if ( ! $phpmailer->getReplyToAddresses() && is_email( $original ) ) {
$phpmailer->addReplyTo( $original, $name );
}
$phpmailer->setFrom( $from, $name, false );
}, 999 );Notes
Set the address to use at the top, or leave it empty to use wordpress@ your domain.
