I waned to get some expert input on a brand new installation of Exchange 2010.
We have 12 physical sites and each site has its own AD forest/domain.
There will be approximately 200 Exchange users/mailboxes between 'all' the AD domains.
There will be 12 different smtp domain names.
What would be the best topology to implement that would enable reliable performance for 'all' the sites??
What exactly would it entail as far as configuration goes??
