title: Indy SMTP satSASL vs satDefault
body: <p>In Indy there are various authentication mechanisms SMTP can use. I have 3-part question:</p>
  
  <p>a) Can I use <code>satSASL</code> all the time instead of <code>satDefault</code> or is there a case where <code>satDefault</code> is better?</p>
  
  <p>b) And what is the best order of SASL mechanisms from most secure to least secure. My order so far is:</p>
  
  <ul>
  <li>IdSASL_CRAMSHA1</li>
  <li>IdSASL_CRAMMD5</li>
  <li>IdSASL_Digest</li>
  <li>IdSASL_Login</li>
  <li>IdSASL_Plain</li>
  <li>IdSASL_OTP</li>
  <li>IdSASL_SKey</li>
  <li>IdSASL_External</li>
  <li>IdSASL_Anonymous</li>
  </ul>
  
  <p>c) I plan to use the above list for POP3, SMTP, NNTP and IMAP. Have I missed a SASL mechanism in it and is there a case where the above order may not be good for the 4 mentioned protocols.</p>
  
  <p>Thank you in advance.</p>
