This function will add text to the email message. An email must be created by smtpNew before text can be added.
Once the text is added, it cannot be removed again, and the only option is to cancel the email (with smtpCancel) and start over again.
Note: the email message can only contain 4095 characters of text.
Input:
Handle : INT
The handle for the email.
Message : STRING
The text message to add.
Returns: INT
The number of free characters remaining.
