WordPress sender fix

Fix WordPress wp_mail From address and DMARC alignment.

WordPress mail often fails or lands in spam when the From address uses Gmail, Yahoo, Outlook, or a domain that is not verified with the sending provider.

Sender alignment matrix

Current From	Risk	Recommended correction
`user@gmail.com`	Free-mail sender policy	Use `wordpress@example.com`; put user email in Reply-To.
`noreply@otherdomain.com`	Provider verification mismatch	Verify that domain or switch to the site domain.
`wordpress@example.com` without DKIM	Spam/filtering risk	Enable provider DKIM/SPF for the sending domain.

Safe WordPress filter pattern

// Pattern to verify in your environment.
add_filter('wp_mail_from', function () {
    return 'wordpress@example.com';
});

add_filter('wp_mail_from_name', function () {
    return 'Example Website';
});

Testing workflow

Send a plain `wp_mail()` test to a known-good mailbox.
Check provider logs for acceptance or rejection.
Then test the contact form or WooCommerce template.
