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.
