Confirmation email name is ‘WordPress’

When I send a confirmation email, my clients are receiving the email from WordPress <[email protected]>. I have tried to change this to “Lindon Labs”, to “[email protected]” and “Lindon Labs <[email protected]>” but unfortunately, the sender is always listed as “WordPress.” I think that, because of this, many email accounts are blocking the email or sending it to spam. How do I change the sender name appropriately?
