J2SE Version (please include all output from java -version flag):
  Java 1.5.0_03

Does this problem occur on J2SE 1.4.x or 5.0.x ? Yes / No (pick one)
  Works fine with 1.4 and IPv4

Operating System Configuration Information (be specific):
  Windows 2003 without a SP
  Mail Server is Exchange 5.5 with IPv4

Bug Description:
  Each connect to an IMAP-Account opens a new ServerSocket.
  After some time there are no free socket ports and get an exeptions like:
 
  javax.mail.MessagingException: Address already in use: JVM_Bind;
    nested exception is:
  java.net.BindException: Address already in use: JVM_Bind
   at com.sun.mail.imap.IMAPStore.protocolConnect(IMAPStore.java:441)
   at javax.mail.Service.connect(Service.java:233)
   at javax.mail.Service.connect(Service.java:134)
 
Steps to Reproduce (be specific):

 run attached IMAP_Socket_Test program 2-3 minutes
  until the exceptions occur.
 
  In this time you can see with "netstat -na" on an other console the
  increasing number of ServerSockets.
 
  To run the test "IMAP_Socket_Test" you need to edit the file IMAP_Socket_Test.bat. You need to fill in the host, accont and password of an existing IMAP-Account.
