Do you make use of the custom whiltelist? Or the Auto-Generated Whitelist? The auto-generated one keeps a track of the desitation address of all emails sent out by your users. So, it assumes if I am sending them an email, then they're reply emails should be ok so I won't check them for spam.
You can then go through this list and add some to your custom whitelist. The auto whitelist remembers 2000 (I think) addresses. When it reaches this, it removes the first 50 and then keeps monitoring. I think moving the spam into another mailbox and putting some of the responsibility back on the users to let me know what they would like whitelisted is a good thing. At first I had a lot of requests but hardly any anymore. We also wrote a custom script that emails us every morning a .csv file listing all of the emails from .com.au addresses that was marked as spam. My boss looks through it each morning and emails me a list of addresses he wants whitelisted. Because we are an Australian company most of our whitelist is .com.au addresses. We originally had the script only telling us about spam from .com.au that was bigger than 50k in size, but we changed it to all emails recently. There are around 200-300 a day. But the responsibility isn't on me to manage this. I simply copy and paste into SMS SMTP and hit save. Couldn't be any easier. If users complain about false-positives my opinion is, "Well, if you don't like it, we will just let all spam through and not check any. Do you want that?" I don't say it in those words, but to that effect. They understand my point very quickly and stop hassling me. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Kevin Bilbee Sent: Saturday, 24 July 2004 10:42 AM To: [EMAIL PROTECTED] Subject: [IMail Forum] SAV Mail Gateway [WAS Anti-virus] > We use Symantec Mail Security for SMTP Gateways.

What I think you mean is that you have the ability to protect 4000 mail accounts not licenses to install the gateway product 4000 times.

I am glad you are getting such great results with the heuristics but I have not had such good luck. It regurally false positives for us so I have set it to level 1 and catch the header of "Bulk: 99" with declude at 98 they were all false positives. Also the heuristics have a date of april on our box. What is the date of your heuristics file?
