A:
to configure this.
First, apply a Dynmic DNS account from www.dyndns.org or other dynimic DNS provider, such as exchange.dyndns.org
Second, configure MX record in the setup page of Dyndns's web site.
Third, configure a dynamic dns client on that server so that your ip will update to the Dyndns's web site.
After that, configure exchange to accept mail to xxx@exchange.dyndns.org.
Q47:
请问Exchange视讯版在防火墙内的话应该开那些埠才可正常运作呢？
A:
Exchange Server 2003已不提供视讯版了！
To allow exchange to pass through firewall, please reference this KB to open ports on firewall: XGEN: TCP/UDP Ports Used By Exchange 2000 Server
