Since you cannot change the Exchange 5.5 SMTP banner, you will need to explore the following options: 1) Install a Windows Server (preferably 2003) and setup IIS SMTP as the Internet accessible SMTP gateway for your 5.5 server. After the server has been patched behind a firewall, I would recommend placing this SMTP gateway in your DMZ with only SMTP traffic over port 25 accessible from the Internet and your LAN (or wherever your Exchange server logically resides). 2) Install a 3rd party SMTP gateway, such as an email appliance (TrendMicro, Barracuda, Ironport, FortiMail, etc.) or an standard SMTP MTA like Postfix, qmail, or Exim. ...D
