This is a screenshot of a Netscape browser window showing
what you see by default when you first run the sendMail tag 
sample application.

There are empty fields for "Host", "From", "To", "Cc", and
"Bcc"; a "Subject" field that says "Hi"; a message field
that says "How are you!"; and a "Send" button to send the
message after you put appropriate information in the fields.
