I'm running an Exchange 2003 server (no laughing PLEASE) with a Sonicwall NSA 3500. I'm using Sonicwall's Anti-Spam currently.
I have been recently tasked with blocking or stripping attachments of certain file type. Specifically images, .JPG, .TIF, etc.
I have started looking at cloud based security product like McAfee SaaS email protection and an appliance such as Sonicwall's ESA 3300. These will block or strip images incoming and outgoing attachments that are images. But I was wondering if anyone had any decent suggestions on how I might accomplish this locally on Exchange.
Another words strip or block an internal person from sending another internal person a .JPG.
I know Anti-Virus products usually do this, but is there something lighter weight or better that might include blocking offensive language, sexual language, etc. Basically similar to what McAfee & Sonicwall offer but for local emails.
