Tracking Center

i cannot see our local email traffic (internal domains) when i check tracing center.
do the internal mails go through PMG?
the Tracking center uses the system-log to gather its data - check for messages from your internal systems in /var/log/syslog
-> the should show up in the Tracking center as well...
 
Should we change port and hostname over exchange server ?
You need to change the exchange configuration to send mails to PMG (and not to the internet directly) - search for Exchange Smart Host...

I hope this helps!
