I've got an Exchange server on a site called A.
I've got a Sendmail Box on a site called B. (Without AD)

So Sendmail on B forward every message to Exchange on A for users of the
site A.

When I try to add a Domain Controller for the site B (sites are well defined
in Active Directory Sites), It completes succeed. (I DO NOT INSTALL EXCHANGE
ON THIS SERVER)
But then, Sendmail forward sometimes emails to Exchange on A (so it works
fine), sometimes to DC on B (so i get a "user unknow" error).
I don't understand why Sendmail starts to forward emails to this server.
Sendmail is also a slave DNS server for Exchange in A....but MX is ok and go
to Exchange in A and never to DC in B.

Any idea?

I've found the answer.
In fact, I had to add an MX entry on the DNS server on A.
It was working before without mx entry caus there was only one server inside
the AD domain.
