php mail() function error problem

mail("$to", "$subject", "$msg", "$headers");

Error:

Warning: mail() [function.mail]: SMTP server response: 550 5.7.1 Unable to relay for atoat@sina.com in C:/webserver/htdocs/www/mail.php on line 14

php.ini configuration

[mail function]
; For Win32 only.
SMTP = localhost
smtp_port = 25
; For Win32 only.
sendmail_from = atoat@163.com

already installed I found the SMTP service that comes with windows

After searching for a long time, I found that I need to add the local IP address in the relay option of the SMTP service

Virtual server->Properties->Access-> ;Relay

Select "Only the following list" =>"Single computer"=>Add the local address of 127.0.0.1

There is no problem with the program, but there is nothing in the inbox I received the message immediately.

I didn’t receive it because my machine is on the internal network and cannot send emails to the external network.

Solution:

Make a port mapping on the gateway and map port 25 to the local machine. Or the machine has a public IP.
