Netscape Messaging server will not de-allocate memory that is used to store the RCPT TO information for an incoming email. By sending enough long RCPT TO addresses, the system can be forced to consume all available memory, leading to a denial of service.

You can test "YOUR" Netscape Messaging Server 3.6SP2 for NT

whether vulnerable for too much RCPT TO or not.
