<quote> Does the vulnerability affect the SMTP service in Exchange Server 5.5?
No. Exchange 5.5, even if installed on Windows 2000, uses its own SMTP service, which is not affected by the vulnerability </quote> <Siegfried /> > -----Original Message----- > From: Orr, Dale [mailto:[EMAIL PROTECTED]] > Sent: Thursday, February 28, 2002 1:22 PM > To: Exchange Discussions > Subject: RE: Alert:Microsoft Security Bulletin - MS02-012 > > This one is giving me a headache -- I have Exch 5.5 running on a Win2k > server.
