To configure an SSH tunnel for SMTP traffic, follow these steps:
1. Open a terminal window on your local machine.
1. Type the following command to start the SSH connection and create the tunnel:
`ssh -L 25:localhost:25 username@remote_host` Replace “username” with your username on the remote host and “remote\_host” with the hostname or IP address of the remote host.1. Enter your password when prompted.
1. Once the SSH connection is established, you can open your email client and configure it to use SMTP server “localhost” on port 25.
1. Your email client will now send all SMTP traffic through the SSH tunnel to the remote host, securely encrypted.
Note: Some email clients may require additional configuration to specify that the SMTP server requires authentication. Consult the documentation for your email client for detailed instructions.
