Hi

my customer environment has  4 Exchange 2010 server SP1; 2 cas\hub exchange  and 2 Mailbox. Mailflow is ok. I have implement DAG and cas arrary with NBL. The Smtp relay server (exchange 2003).

All the exchange 2010 patched with rollup3 on w2k8R2 SP1.  

Application servers uses the MX record to send system messages to users.
For this account, tpann@XXXXXX, sometimes, the mails can be resolved as internal, showing as Announcement Publisher but sometimes it cannot resolve and show as tpann@XXXXXX (Like an external email).Also I checked SMTP message tracking logs, it seems those mails that go through SMTP-1 can resolved properly and those that go through exchange 2010, could not resolve the names.

In addition i found this  link

That's the way it works by default, to not resolve addresses to the GAL if they are sent via an anonymous SMTP connection. Check out the article below for how to setup a new connector that will resolve the sender's address to the GAL.
