Hi experts..
We currently have 1 internet connection (ISP1)
I have an exchange server (cas, hub, mbx role) currently setup with 1 send connector smpt * cost (1).
we recently bought another backup connection (ISP2)
How can I setup exchange so that if ISP1 goes down Exchange will send mail thru ISP2
exchange is setup with 2 nics
nic1(ISP1) /ip address /default gateway 1
nic2 (ISP2)/ ip address /default gateway 2
I've updated our dns so that:
Mail.mycompany.com to point to Nic1 (ISP1)
mail2.mycompany.com to point to Nic2 (ISP2)
we currently do not have a smarthost.
Postini currently does our spam filtering so the recieve connector are configure to receive from Postini's ip
I can configure another send connector with a different cost but it does not allow me to bind it to a particular nic.
so how does exchange know if Nic1 (ISP1) goes down to send thru Nic2 (ISP2)
thanks for any insight...
