body: <p>In Sendmail Jilter, what does various Abbreviations mentioned in JilterConstants mean ?
  like:
  <code>SMFIC_HEADER</code>, <code>SMFIR_CHGHEADER</code> etc.</p>
  <p>Official documentation doesn't have any details for class <code>JilterConstants</code></p>
  <p><a href="http://sendmail-jilter.sourceforge.net/apidocs/index.html" rel="nofollow noreferrer">http://sendmail-jilter.sourceforge.net/apidocs/index.html</a></p>
  <p>However i was able to find what each flag is used for:</p>
  <p><a href="https://github.com/tachtler/jilter-InfoMilter/blob/master/com/sendmail/jilter/JilterConstants.java" rel="nofollow noreferrer">https://github.com/tachtler/jilter-InfoMilter/blob/master/com/sendmail/jilter/JilterConstants.java</a></p>
  <p>But i am interested in full form of those flags.</p>
  <p>For <code>SMFIC_HEADER</code> I assume it may mean &quot;Send Mail Flag .... &quot; But i am looking for an official reference. Thanks.</p>
