After a big research of my sending problem , I found that wp_mail, don’t work.
I worked over the file diagnostic.php on “$r = wp_mail” line
I change this line to mail() function with a differents params, like sender, from, cc, bcc, and the server is not filter my emails.
But when I return to wp_mail() I can’t deliver any mail. No error is returned.
I really can’t found the problem with it.
You have any idea ?
