Windows install clean up PHP Mail failed solution for sending mail through SMTP for Windows

The reason must be in the WordPress PHP Mail send class. Easy Google to reason: the original Windows SMTP service does not support the name of the message format, must be written directly to address@domain.com. So the WordPress class-phpmailer.php in this line

Copy the Code code as follows:

$from [0][1] = $this->fromname;

Comment out on the OK.

The above describes a solution that Windows install clean up PHP Mail failed to send mail through SMTP for Windows, including the Windows install clean up content, which I hope is helpful to a friend who is interested in PHP tutorials.
