Msimple Theme: Configuring SMTP Settings for WordPress

Open the WordPress admin panel, navigate to Appearance > Theme Settings, and you will find the Msimple "SMTP Settings" as shown below.

SMTP Settings

WordPress uses the mail() function by default to send emails. However, most hosting providers disable this function, resulting in low delivery success rates and potential security risks. Email notifications for comments and password recovery require reliable email delivery, so using SMTP is recommended for better stability and security.

Note: If you are already using another SMTP plugin, do not enable the Msimple theme's SMTP feature (it is disabled by default). In short, choose either a dedicated SMTP plugin or the built-in SMTP settings in the Msimple theme (recommended).

Here are the SMTP server addresses and ports for common email providers:

Email Provider	SMTP Server Address	Non-SSL Port	SSL Port
163.com	smtp.163.com	25	465 or 994
126.com	smtp.126.com	25	465 or 994
qq.com	smtp.qq.com	25	465 or 587
NetEase Corporate Email	smtp.qiye.163.com	25	994
Tencent Corporate Email	smtp.exmail.qq.com	25	465

Important Considerations

• Ensure that SMTP functionality is enabled in your email provider's backend settings before configuring it.
• Most providers now require an independent email password (not your standard login password) for SMTP authentication.
• Some hosting providers block outgoing connections on port 25; it is recommended to use the SSL port 465 instead.
• Any error in the SMTP settings will prevent email delivery. Before configuring, test your email credentials using a local client like Foxmail to ensure accuracy.
