Hi Thufir,
it is not clear (at least to me) what you would like to achieve ... :-)
According to Wikipedia
"NNTP - It resembled the Simple Mail Transfer Protocol (SMTP), but was
tailored for exchanging newsgroup articles."
A simple road map which could help you
+) have a look http://commons.apache.org/email/userguide.html
+) have a look at the test code
at this point you should have a good idea what you can do with commons-email
Regarding headers - if you would like to add custom (aka non-SMTP)
headers you should use the "X-headers" approach (see
http://www.systemnetmail.com/faq/3.3.4.aspx), which are prefixed with a
"X-" to keep SMTP server and clients happy.
Cheers,
Siegfried Goeschl

btw. there exists the commons-email component to send mime messages in a

While it does help, it still seems to bring up the same type of
MessagingException and merely moves the problem around:
compile:

The problem being that the String representation of headers returned by
String headers = read(client.retrieveArticleHeader(i));
seems fundamentally incompatible with any sort of javax.mail.Message, or
anything related. there must be a way to turn that String of headers
into legitimate headers for a Message, but how?
I'm quite sure that it's possible to massage the message, if you'll
forgive me for abusing that quote, into a Message of one variety or
another. The question is, how? My ArticleReader.java to follow:
package net.bounceme.dur.nntp;
import java.io.BufferedReader;
import java.io.PrintWriter;
import java.util.Properties;
import java.util.logging.Logger;
import javax.mail.Message.RecipientType;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.MimeMessage;
import org.apache.commons.mail.util.MimeMessageUtils;
import org.apache.commons.net.PrintCommandListener;
import org.apache.commons.net.nntp.NNTPClient;
import org.apache.commons.net.nntp.NewsgroupInfo;
public final class ArticleReader {
private final static Logger LOG = Logger.getLogger
(ArticleReader.class.getName());
public ArticleReader(Properties p) throws Exception {
NNTPClient client = new NNTPClient();
client.addProtocolCommandListener(new PrintCommandListener(new
PrintWriter(System.out), true));
client.connect(p.getProperty("host"));
NewsgroupInfo newsgroupInfo = new NewsgroupInfo();
client.selectNewsgroup(p.getProperty("newsgroup"), newsgroupInfo);
Session session = Session.getDefaultInstance(p);
String protocol = p.getProperty("protocol");
String host = p.getProperty("host");
int port = Integer.valueOf(p.getProperty("port"));
String username = p.getProperty("username");
String password = p.getProperty("password");
Transport transport = session.getTransport(protocol);
transport.connect(host, port, username, password);
for (long i = newsgroupInfo.getFirstArticleLong(); i <
newsgroupInfo.getLastArticleLong(); i++) {
String headers = read(client.retrieveArticleHeader(i));
String body = read(client.retrieveArticleBody(i));
String sb = headers + body;
MimeMessage message = MimeMessageUtils.createMimeMessage
(session, sb);
message.setRecipients(RecipientType.TO, p.getProperty
("recipient"));
transport.sendMessage(message, message.getAllRecipients());
}
}
public String read(BufferedReader br) throws Exception {
StringBuilder lines = new StringBuilder();
String line;
while ((line = br.readLine()) != null) {
lines.append(line).append("\n");
}
br.close();
return new String(lines);
}
}
Any and all suggestions appreciated.
thanks,
Thufir
