As per the title, being able to set the default from email address and name would in my opinion be a worthy addition.
Not tested this yet but I assume something like so would do the trick:
add_filter('wp_mail_from', 'ctm_new_mail_from');
add_filter('wp_mail_from_name', 'ctm_new_mail_from_name');
function ctm_new_mail_from($old) {
return '[email protected]';
}
function ctm_new_mail_from_name($old) {
return 'DOMAIN Support';
}
