Every time someone submitted a comment on your blog, signed up as a user or did anything that required WordPress to generate and send an e-mail, by default the “From Name” in that message appeared as “WordPress” and “From” address was “wordpress@your-domain.com”.
if you want to change this, just copy the below code to your functions.php
/** changing default wordpres email settings */
add_filter('wp_mail_from', 'new_mail_from');
add_filter('wp_mail_from_name', 'new_mail_from_name');
function new_mail_from($old) {
return 'your email address';
}
function new_mail_from_name($old) {
return 'your name or your website';
}
