java mail Store.connect hangs - doesn't timeout

I'm using plain old java mail (mail-1.4.1.jar - JVM 1.6.0_03-b05) to connect to an IMAP store:

Session mailSession = Session.getInstance(new Properties(), null);
Store store = mailSession.getStore("imap");
store.connect(host, user, pwd); // Hangs here
folder = store.getFolder("INBOX");
folder.open(Folder.READ_WRITE);
...

Problem is, occasionally the thread hands at store.connect and never returns.

There is no mention of timeout settings in the javamail spec and I cannot find any suitable 'setter' methods on either Session or Store.

Any suggestions welcome.

See the javadocs for the com.sun.mail.imap package for the properties you can set to control (among other things) timeouts. Oh, and you probably want to upgrade to the latest version of JavaMail.
