title: IMAP folders diff?
body: <p>I'd like to "diff" two IMAP folders (on two different servers) to compare spam filters, I'd like to have a command line tool (linux) to get just the headers (not the whole dir, e.g. using 'isync' or similar), something like this:</p>
  
  <p>$ imapget --subjects -p=password user@server</p>
  
  <p>or this:</p>
  
  <p>$ imapget --format "$DATE - $FROM - $SUBJ" -p=password user@server</p>
  
  <p>('imapget' cmd is fictional)</p>
  
  <p>What would you suggest?</p>
  
  <p>Thank you</p>
