Outside senders are receiving this error when sending mail to us. This issue has appeared multiple times since 5.4 was released, but I still have a few questions:

1.) This message points to a recommendation to change the startup script to include 'SUPPLPARAMS="--TLSServerHelloExtensions NO"': http://mail.stalker.com/lists/cgatepro/Message/102285.html

How is this done on a Windows install?

2.) This is from a large Exchange install. Is there a software update that the senders can apply to the exchange server to fix this? Presumably this has been fixed and they have not applied the update? If so, I will point them to it.
