     - cust_main_invoice - Invoice destinations for email invoices.  Note that a customer can have many email destinations for their invoice (either literal or via svcnum), but only one postal destination.
      
        - destnum - primary key
        
 - custnum - customer
        
 - dest - Invoice destination.  Freeside supports three types of invoice delivery: send directly to a service defined in Freeside, send to an arbitrary email address, or print the invoice to a printer and have someone send it out via snail mail.  Freeside determines which method to use based on the contents of the dest field.  If the contents are numeric, a svcnum pointing to a valid service is expected in the field.  If the contents are a string, a literal email address is expected to be in the field.  If the special keyword `POST' is present, the snail mail method is used (which is the default if no cust_main_invoice records exist).  Snail mail invoices get their address information from cust_main and are printed with the printer defined in the configuration files.
