Hi.
Are you using SEP - as you seem to be reffering to Symantec System Centre which I think is in SAV not SEP. We could never get reporting to work on SAV anyway, in fact no one could fix this for us. And when it worked for the first month when we deployed SAV, the RISK report was inaccurate anyway
for SEP
under the console you can tell the SEPM where and how to connect to your mail server.
click on 'Admin' from the SEPM console - it's on the left hand side.
then at the bottom click on 'Servers'
now up at the top you should see information about your SEP setup.....
Right click on the server where SEPM is installed and select 'Edit Properties'
From here you can see the 'Mail Server' tab - enter the details necessary for your mail server -
