IMAP/TLS Problem in connecting using java mail api.

Thanks for reply. After adding that method I am getting following exception

Hi All,

I have a IMAP4 server running with TLS authentication switched on and have self signed certificate. do not want toinstall certificates so I tried DummySSLSocketFactory and DummyTrustManager provided by SUN.

Standalone programm works correctly. Please see code below. But If I put the code into Tomcat throws exception. Any clue?

private void receiveEmails() throws NoSuchProviderException, MessagingException, IOException {

// String host, name, passwd;

String host = "HOST_NAME";

String name = "USER_ID";

String passwd = "PASSWORD";

Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());

java.security.Security.setProperty("ssl.SocketFactory.provider", "DummySSLSocketFactory");

// Get a Properties object

Properties props = System.getProperties();

props.setProperty("mail.imap.socketFactory.fallback", "false");

props.setProperty("mail.imap.starttls.enable", "true");

Session session = Session.getDefaultInstance(props, null);

session.setDebug(false);

Store store = session.getStore("imap");

try {

store.connect(host, name, passwd); // exception here

System.out.println("store connected");

} catch (Exception e) {

// System.out.println("Error :" + e.toString());

e.printStackTrace();

System.exit(1);

}

}

Inside Tomcat :- Same code in tomcat throws exception. Also it does not give call to DummySSLSocketFactory.

Code and Exception.

public void doExecute(JobExecutionContext context) {

String host = "lxeext12.deutsche-boerse.de";

String name = "capacity";

String passwd = "capacity";

Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());

Security.setProperty("ssl.SocketFactory.provider", com.deutscheboerse.comxerv.common.service.timer.DummySSLSocketFactory.class.getName());

// Get a Properties object

Properties props = System.getProperties();

props.setProperty("mail.imap.socketFactory.fallback", "false");

props.setProperty("mail.imap.starttls.enable", "true");

try {

Session session = Session.getDefaultInstance(props, null);

session.setDebug(true);

Store store = session.getStore("imap");

store.connect(host, name, passwd); // exception here

System.out.println("store connected");

}catch (Exception e) {

e.printStackTrace();

}

}

If I change the bold marked line below then.

public void doExecute(JobExecutionContext context) {

String host = "lxeext12.deutsche-boerse.de";

String name = "capacity";

String passwd = "capacity";

Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());

// Get a Properties object

Properties props = System.getProperties();

props.setProperty("mail.imap.socketFactory.class", com.deutscheboerse.comxerv.common.service.timer.DummySSLSocketFactory.class.getName());

props.setProperty("mail.imap.socketFactory.fallback", "false");

props.setProperty("mail.imap.starttls.enable", "true");

try {

Session session = Session.getDefaultInstance(props, null);

session.setDebug(true);

Store store = session.getStore("imap");

store.connect(host, name, passwd); // exception here

}catch (Exception e) {

e.printStackTrace();

}

}

- It calls the DummySSLSocketFactory but throws following exception.

Exception is:-

javax.mail.MessagingException: Unrecognized SSL message, plaintext connection?;

nested exception is:

javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connecti

Thanks for your reply.

Security turned off is not an option not even for testing :-(

I tried to grant the permissions inside the the catalina.policy file inside tomcat with following lines.

grant {

permission java.io.FilePermission "file:${catalina.home}\webapps\my-app\WEB-INF\lib\mail-1.4.jar", "read";

permission java.io.FilePermission "file:${catalina.home}\webapps\my-app\WEB-INF\lib\java.activation-activation-1.1.jar", "read";

// following to use IMAP

permission java.net.SocketPermission "MY_HOST:143", "connect,resolve";

// following needed if System.getProperties() is used

permission java.util.PropertyPermission "*", "read,write";

};

Still same exception happens.

Any clues?

Best Regads,

I learnt from Bill that LOGINDISABLED just means that the simple LOGIN command that sends plain text passwords is disabled. After STARTTLS the new CAPABILITIES will show that LOGIN is allowed.

Please turn on the SSL/TLS debugging options

(referenced in SSLNOTES.txt) and see if that provides any clues.

It's not a good sign that the first command after STARTTLS causes the

connection to drop. Bill suspects that something is going wrong with the TLS

communication.
