Configure the settings for sending or receiving an Email Securely Using SSL/TLS.
Follow the steps below to configure the POP3/IMAP4/SMTP settings for sending or receiving email via an email server that is using SSL/TLS communication.
Check if a CA Certificate issued by the Certificate Authority (CA) that signed the server certificate is imported.
Contact your network administrator or your Internet Service Provider (ISP) to confirm if importing a CA Certificate is necessary.
Start your web browser.
Type "http://machine's IP address/" in your browser's address bar (where "machine's IP address" is the machine's IP address).
E.g. http://192.168.1.2/
If you are using a Domain Name System or enable a NetBIOS name, you can type another name, such as "SharedPrinter" instead of the IP address.
E.g. http://SharedPrinter/
Type a password if you have set one, and then press (Right arrow key).
Click Network.
Click Protocol.
Click Advanced Setting in POP3/IMAP4/SMTP.
Choose the certificate you want to export and click Export.
Configure the POP3/IMAP4/SMTP settings.
If you choose SSL or TLS and want to check if the CA Certificate works correctly, check the box for Verify the Server Certificate.
If you choose SSL or TLS for SMTP, POP3, or IMAP4, the Port value will be changed to match the protocol.
To change the port number manually, type the port number after you choose SSL or TLS for the SSL/TLS settings.
You must configure your machine's POP3/IMAP4/SMTP communication method to match the method used by your email server. For details about your email server settings, contact your network administrator or your ISP.
