Prerequisites

Before configuring a third-party email client, verify the following account settings:

Server Addresses and Port Information

Protocol selection:

  • IMAP (Recommended): Syncs emails between clients and the web interface. Best for multi-device use.

  • POP3: Downloads emails to the local device only. Best for local archiving.

Important

Always use SSL-encrypted ports for data security.

The official Alibaba Mail server addresses, such as imap.qiye.aliyun.com, pop.qiye.aliyun.com, and smtp.qiye.aliyun.com, have a valid SSL certificate issued by a globally trusted certification authority. Use the SSL-encrypted ports in the following table to establish a secure connection without deploying a certificate yourself. If you use a custom domain as the server address, purchase and upload your own SSL certificate as described in the FAQ "Do I need to configure an SSL certificate when using a custom domain as the server address?" in this topic.

FAQs

  • "Username or password error" appears during configuration, but I confirmed the password is correct.

    • Cause: The account uses a third-party client security password. The regular mailbox logon password does not work.

    • Solution: Generate a third-party client security password and use it as the client password.

  • Cannot connect to the server after checking SSL?

    • Cause: SSL is enabled but the port is still set to a non-encrypted value (110 or 143).

    • Solution: Change the port to the SSL-encrypted port: 993 for IMAP or 995 for POP3.

  • Do I need to configure an SSL certificate when using a custom domain as the server address?

    • Cause: When you use a custom domain (for example, imap.yourdomain.com) as the IMAP, SMTP, or POP3 server address and enable an SSL-encrypted port (993, 465, or 995), you must purchase and upload an SSL certificate yourself. Upload the certificate at Console > Enterprise Customization > Domain Management > SSL Certificate Management. If no certificate is configured, the client may fail to establish an SSL connection due to certificate verification failure.

    • Solution: When you use the official Alibaba Mail server addresses (such as imap.qiye.aliyun.com), an SSL certificate is preconfigured and no additional setup is required. When you use a custom domain, upload a valid SSL certificate in the console as described above before enabling the SSL-encrypted port.
