Assume we co-locate our servers at different ISPs, say bezeqint.net and
netvision.net.il 
Both ISP, obviously, have different IP scopes, let's call them net1 and
net2.

So, 1st mx sits in net1, and 2nd - within net2.
Both mx share same hostname but have different IP.

Now, assume that a customer's comes from net1.
I'd like him to always choose 1st mx, unless it's down, then it switches to
2nd mx.

I think that a problem here would be syncronization of mailboxes.
Or, am I wrong?

Thanks!


Best,
