Hi Everyone, I've been experimenting with running Exchange 2007 and Windows Server 2008 solely on IPv6 and its all up and stable - other than a few teething problems it successfully sends to my other SixXS Exchange 2007 and Postfix instances. Exchange 2007 still has a few issues and I was wondering if you'd help out by hammering this test server with incoming and Outgoing mail to your own IPv6 enabled MTA's so we can see if there are any other issues that I've yet to find. I've enabled Outlook Web Access and its available here: https://exchange.networksaremadeofstring.net/owa User accounts: Test1 p@s5w0rd1 Test2 p@s5w0rd2 Test3 p@s5w0rd3 Test4 p@s5w0rd4 Thanks to anybody who helps Note: This machine has no IPv4 or 6to4 capabilities. I'm sure I don't have to say it but don't use this to send unsolicted mail or to send mail to MTA's you don't control etc
