title: Sendmail authentication failed [# in password]
body: <p>When sendmail is configured with password that starts with the character <code>#</code>, authentication is failed. Sendmail throwed an error that "AUTH=client, available mechanisms do not fulfill requirements". </p>
  
  <p>Is this is a known issue.?
  Is that a restriction with sendmail or ssl authentication or rules parsing?</p>
  
  <p>Sample <em>default-auth-info</em> file :-</p>
  
  <pre><code>sendmailtest@gmail.com
  sendmailtest@gmail.com
  #12345678
  smtp.gmail.com:587
  LOGIN PLAIN DIGEST-MD5 CRAM-MD5 NTLM
  </code></pre>
  
  <p>LINUX platform</p>
  
  <p>Sendmail version : 8.14.0</p>
  
  <p>sasl version    : 2.1.22</p>
  
  <p>Thanks in advance for the help..</p>
