When i in local network is xxx.local, but on the external i will use xxx.com.hk which MX record need to add?

How is your mailflow configured? MX record -> A record -> external IP address of FW -> forward to exchange server? Is this correct? Jonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog
