<b>parameter: </b><em>str-from</em> - The email address of the sender.<br/>
<b>parameter: </b><em>str-to</em> - The email address of the recipient.<br/>
<b>parameter: </b><em>str-subject</em> - The subject line of the email.<br/>
<b>parameter: </b><em>str-message</em> - The message part of the email.<br/>

<p><b>return: </b>On success <tt>true</tt>, on failure <tt>nil</tt>.</p>
 In case the function fails returning <tt>nil</tt>, the function
 <tt>SMTP:get-error-text</tt> can be used to receive the error text.
<b>example:</b><blockquote><pre> (SMTP:send-mail "jdoe@asite.com" "somebody@isp.com" "Greetings" 
   "How are you today? - john doe -" "smtp.asite.com" "jdoe" "secret") 
 This logs in to the server, tries to authenticate using the username 'jdoe' and password 'secret' (if supplied), 
 and sends an email with the format: 

  From:    jdoe@asite.com 
  To:      somebody@isp.com 
  Subject: Greetings 
  Message: How are you today? - John Doe - </pre></blockquote>

 <p>Useful for attaching binary data such as images. Converts the data into base64
 and chops it up so that the lines are not longer than 76 characters long, making
