Answer 1

JavaMail is an oracle library that provides mail services and mail related services (like parsing conventional & MIME messages) in the javax.mail package. Additionally Apache has a Commons Email library for mail handling.

In the JavaMail api, a simple way to parse a string containing an email message (which may or may not be explicitly MIME) would be as follows

String content = ... Session s = Session.getInstance(new Properties()); InputStream is = new ByteArrayInputStream(content.getBytes()); MimeMessage message = new MimeMessage(s, is); 

and parsing the headers could be done like this

message.getAllHeaderLines(); for (Enumeration<Header> e = message.getAllHeaders(); e.hasMoreElements();) {     Header h = e.nextElement();     h.getName();     h.getValue(); }

I have had problems with JavaMail (it fails to parse some email messages that it should).

I have had much better results with Mime4J.
