troubleshoot messages that cannot be sent
the inability to send a message is a common problem with WordPress, typically because the server does not support the PHP mail () function, and there are usually two ways to fix it.

ps:wordpress Send mail must use the Wp_mail () function instead of calling the PHP SMTP class or other functions directly.

First, configure the server environment

If you are using a VPS, you can configure the server to enable the server to support the mail () function, according to each person's situation can be found by the search engine configuration method, here is not detailed.

Second, the use of SMTP

The second is to use SMTP to send mail, but also I recommend a method. SMTP is the use of other free mail service provider's server to send mail, so it is not easy to identify as spam in this way.

OK, let WordPress support SMTP recommended is the use of WP SMTP plug-in, installed in the background to configure your SMTP information, I use QQ mailbox.

Once configured, you can test to see if the configuration is successful at the bottom.
