If your only choice is to parse an email, then an application of some kind
(java, C, perl) is probably the better solution. The primary purpose of a
servlet is to provide a service in response to a request. That said, if you
really want to provide instantaneous processing of a reply from a verification,
then provide a URL in the email which causes the server to execute or call the
server-side processor (i.e., could be servlet, or cgi, or jsp, etc.). If you
know for sure that all user email clients can handle HTML encoded email, you can
put a form in the email with submit buttons that sends a request to your
servlet.
I recently subscribed to this list and the URL method is how Sun processed my
request. I sent in the subscribe message. The list server responded with me an
email which provided a URL. When I went to the URL in the message, a cgi process
handled the request.
