SFWR: Adjusting mail size

[Burleigh Angle]

One of my users wants to send out attachments that are 20 MGB or more.
These are PowerPoint files that he wants to send to clients.  We are running
Exchange server 5.5 in NT 4.0 behind a Raptor firewall.  When attempting to
send out this large a file, a reply comes back from the system administrator
to the effect that it is beyond the 5MGB limit.  How do I change this
limitation?
