Hi Community,
I have a client with an ESA as the first mail server coming from the Internet and last one on the path out.
This client is a University and the default ESA settings are not stopping much of the spam received.
What I would like to ask is any recommendations or reference to deploying the ESA in a University where the recipients are just too many and too dynamic to maintain in a list (LDAP), and any guidance or best practices.
Thank you very much,
Federico.

Hi Federico,

2. Verify that you are receiving anti-spam rule updates- Go to MONITOR > MESSAGE TRACKING

Look for the Antispam engine (CASE) verdict. Example:
