title: how exim show password on log files
body: <p>I want to debug all auth session.</p>
  
  <p>For example on <strong>/var/log/exim/mainlog</strong> display auth error like this;</p>
  
  <blockquote>
    <p>login authenticator failed for (xx) [x.x.x.x]: 535 Incorrect
    authentication data (set_id=xxx)</p>
    
    <p>login authenticator failed for (xx) [x.x.x.x]: 535 Incorrect
    authentication data (set_id=xxx)</p>
    
    <p>login authenticator failed for (xx) [x.x.x.x]: 535 Incorrect
    authentication data (set_id=xxx)</p>
  </blockquote>
  
  <p>but i want to display password too like this;</p>
  
  <blockquote>
    <p>login authenticator failed for (xx) [x.x.x.x]: 535 Incorrect
    authentication data (set_id=xxx,<strong>set_pwd=yyy</strong>) login authenticator
    failed for (xx) [x.x.x.x]: 535 Incorrect authentication data
    (set_id=xxx,<strong>set_pwd=yyy</strong>) login authenticator failed for (xx)
    [x.x.x.x]: 535 Incorrect authentication data (set_id=xxx,<strong>set_pwd=yyy</strong>)</p>
  </blockquote>
  
  <p>I changed dovecot conf and added;</p>
  
  <pre><code>auth_verbose = yes
  auth_debug = yes
  auth_debug_passwords = yes
  </code></pre>
  
  <p>but /var/log/exim/mainlog still doesn't display password and /var/log/maillog doesn't give any information about smtp.</p>
  
  <p>So, how can i catch auth error with cleared text password.</p>
