+ <!-- Processor Documentation
================================================== -->
+ <h2>Description:</h2>
+ <p>This Processors consumes email messages via IMAP protocol and
+ sends the content of an email message as content of the
FlowFile.
+ Content of the incoming email message is written as raw bytes
to the
+ content of the outgoing Flow File.
+ </p>
+
+ <p>Since different serves may require different Java Mail
+ properties such properties could be provided via dynamic
properties.
+ For example, below is a sample configuration for GMail:
+ </p>
+ <p>
+ <b>Processor's static properties:</b>
+ <ul>
+ <li><b>Host Name</b> - imap.gmail.com</li>
+ <li><b>Port</b> - 993</li>
+ <li><b>User Name</b> - <i>[your user name]</i></li>
+ <li><b>Password</b> - <i>[your password]</i></li>
+ <li><b>Folder</b> - INBOX</li>
+ </ul>
+ <b>Processor's dynamic properties:</b>
+ <ul>
+ <li><b>mail.imap.socketFactory.class</b> -
javax.net.ssl.SSLSocketFactory</li>
+ <li><b>mail.imap.socketFactory.fallback</b> - false</li>
+ <li><b>mail.store.protocol</b> - imaps</li>

Unfortunately we can't do that, for reasons that there are no sensible
defaults for protocols, only for providers. So if we ever get to something like
ConsumeGmailViaIMAP, then we could eliminate most of not all dynamic
properties, but unless we get into provider specific processors we have to stay
pure to protocols and APIs.
