LocalIP is 192.0.0.1
Don't do this, since this is no local ip address.
Use 192.168.x.x instead!
I am unable to send mails from SME box to exchange server.
I think i need to add DNS entry for exchangelocal.com.
Server-Manager: Configuration -> Domains
and then -> Hostnames and Addresses
But "exchangelocal.com" is not defined in the Internet, so why would you send e-mails from your SME to the exchange server, when no one else can attach the Exchange server this way?
