SMTP server settings

Options - Preferences - Mail Identity - More

Some times a SMTP server requires authentication, you can check the checkbox if you need this option.

If checked you can fill in your smtp server user name, you will be asked for your password when actually sending an e-mail.

Some providers also use a different port, just fill in the different port number to change this.

Pressing the OK button will store the changes and bring you back to the Mail identity window.

The Cancel button will bring you back to the main window, no changes will be made.
