The reason must be in the php email sending class of WordPress. Easily Google the reason: It turns out that the SMTP service of Windows does not support the email format Name
, and must be written directly as address@domain.com. So copy the codeof this line in WordPress’s class-phpmailer.php. The code is as follows:
$from[0][1] = $this->FromName;
The above introduces the solution to the failure of windows install clean up PHP mail to send mail through Windows SMTP, including the content of windows install clean up. I hope it will be helpful to friends who are interested in PHP tutorials.
