Configure SMTP with Personal NetEase Email

​

Why Use Personal NetEase Email?

• No enterprise qualification required: Just register a 163 email with your phone number.
• 5 minutes to enable SMTP: Enable IMAP/SMTP in settings, generate an authorization code.
• Direct integration with superun: Fill in SMTP configuration in environment variables, and you can send emails from workflows and actions.

​

Step 1: Register or Prepare a 163 Email Account

1. Open https://mail.163.com/.
2. Register a new account using your phone number, for example myname@163.com.
3. After completion, you’ll get:
   • Email address: e.g., myname@163.com
   • Login password: Used to log in to webmail

Note: Login password ≠ “Authorization Code” used for SMTP configuration later. These are different.

​

Step 2: Enable IMAP/SMTP and Generate Authorization Code in NetEase Email

1. Log in to your 163 email using a browser (mail.163.com).
2. In the yellow navigation bar at the top of the page, find the “Settings” button to the right of your email address.
3. After clicking “Settings”, a dropdown menu will appear. Click “POP3/SMTP/IMAP” from the menu.
4. After entering this page, in the “IMAP/SMTP Service” section:
   • If not yet enabled, directly check or click “Enable”.

Already Enabled but Sending Fails? Recommend Restarting Service

1. In “IMAP/SMTP Service”, first click “Disable” on the right, confirm to disable.
2. After disabling, click “Enable” again.
3. The system will require identity verification:
   • Usually sends a verification SMS to your bound phone number;
   • Enter the verification code from the SMS to complete verification.
4. After verification passes, the page will display an “Authorization Code”:
   • It’s a random string (e.g., ab3XD9kLm...);
   • Please copy and save it immediately, you’ll need it for SMTP configuration later.

Reminder again:

• Authorization code is only used for IMAP/SMTP login.
• When filling in “password” in applications, use the authorization code, not the password you use to log in to email.

​

Step 3: Confirm SMTP Server Parameters

• SMTP Server: smtp.163.com
• Port: 465 (using SSL encryption)
• Sender Account: Your NetEase email, e.g., myname@163.com
• Sender Password: The authorization code just generated

​

Step 4: Fill in SMTP Environment Variables in superun

• SMTP_HOST: Fill in NetEase SMTP server address → smtp.163.com
• SMTP_PORT: Fill in SSL encrypted port → 465
  If superun or your execution environment has a “Use SSL/TLS” option, remember to check it.
• SMTP_USER: Fill in your NetEase email account → e.g., myname@163.com
• SMTP_PASS: Fill in the authorization code just generated (not the login password)
• SMTP_FROM_NAME: Fill in the “Sender Name” that recipients will see, can be customized, for example: → My Notifications, System Messages, Operations Assistant, etc.

​

Step 5: Send Test Email

1. Create the simplest workflow or action in superun:
   • For example, after triggering, call the “Send Email” action,
   • Recipient should first be another email of yours for testing.
2. Save and execute this workflow, observe if it succeeds:
   • If execution succeeds, you’ll receive the email in your inbox within seconds.
   • If it errors, first check back if there are typos in SMTP settings.

Common Issues Troubleshooting

​

1. Always Getting “Authentication Failed”?

• Check if SMTP_USER is the complete email address (must include @163.com).
• Check if SMTP_PASS is using the latest authorization code.
• Confirm in the “POP3/SMTP/IMAP” page that IMAP/SMTP service is indeed in enabled status.

​

2. Must Port be 465?

• Official recommendation is to use 465 + SSL, which has the best security and stability.
• In very rare environments where 465 cannot connect, you can try 25 or 587, but you’ll need to adjust program and firewall settings simultaneously.

​

3. Can Other NetEase Email Services Like 126, yeah, etc. Be Used?

• Enable IMAP/SMTP in the corresponding email’s settings and generate an authorization code;
• Change the server address to the corresponding one, for example:
  • smtp.126.com
  • smtp.yeah.net
• Other parameters (port, using authorization code) are basically the same as 163.

​

4. Email Subject or Content Shows Garbled Characters (like =20, etc.)?

• Using div layout, some email clients are incompatible
• SMTP content encoding is set incorrectly
• HTML structure is too complex

• Table Layout: Use <table> instead of <div>, all email clients support it
• Standard XHTML: Use correct DOCTYPE declaration
• Inline Styles: Write all CSS within HTML tags
• UTF-8 Encoding: Correctly set character encoding
• Simplified Structure: Remove complex nesting, avoid rendering issues
