The product
               package or 
Trend Micro reseller provides a
               Registration Key for 
ScanMail.
               Registering 
ScanMail entitles
               administrators to standard support and telephone and online technical support. The
               length of the
               maintenance agreement depends on the contract arranged with the 
Trend Micro representative, but is usually 12
               months.
            
Administrators must register and activate ScanMail to enable updates (even when using an evaluation-version
               Activation Code).
