Here is the set up:
Gateway server – Win 2003 – ISA 2004 – Trend Interscan Messaging and security
Front end Exchange server – Win 2003 – Ex 2003 Trend scan mail
Back end Exchange server – Win 2003 – Ex 2003 Trend scan mail
All Internet email is relayed through Gateway Server a dedicated, secure server running Trend Interscan Messaging Security Suite to ensure that email is filtered for viruses and SPAM and to isolate the email infrastructure from inappropriate access.
The email infrastructure has been divided into multiple Routing Groups, covering the major physical sites. This has been done to minimise bandwidth usage between the locations. Routing Group Connectors have been configured in a full mesh topology with Australia as the main gateway for external mail.
We are stopping 10,000 plus spam emails a day but many are still getting through.
Here are the questions:
Would Exchange IMF improve my spam results?
How easy would it be to set up?
Or Should I be looking elsewhere for an anti-spam solution?
