I am using Microsoft Exchange 2003 on server 2003 active directory and just installed Symantecs Mail Security for Exchange version 5.03

Not really sure how it is suppose to work or how long it will take it to work.  I installed it two days ago. Did a manual scan yesterday.  Checked a mail box that I know gets bombed with spam and still had over 500 spams in that box... have I done something wrong?  has it not kicked in yet... Does Symantec require the premium license for it to work well with spam?  

How can I get it to send the spam to spam folders in each mail box?

Do I need to install the spam plugin for outlook on each machine in the office?  Not really sure what this does and doesnt do....

Hi BogiRat,

I use Symantec Mail Security, but have to say it is average at best.

I refused to buy premium anti-spam, it should have been included - spam is not something to make money out of, it is something that needs to be stamped out!

What we ended up doing was putting a GFI Mailsecurity server infront of the exchange server - but that isn't your question...

I do still have anti-spam running from SMS, and I have configured it as below;

Server
 - Configuration
    - Spam Prevention Settings
       - Real Time Blacklists
          - RBL: sbl.spamhaus.org,relays.ordb.org,cbl.abuseat.org,bl.spamcop.net
          - Whitelists: Any addresses you wish to whitelist
          - Recipient Whitelist: Any internal addresses to not be spam protected
       - Heuristics Anti-Spam
          - Enable
          - Disable all rejects
          - Prevent delivery to original recipient if SCL >6
          - Deliver to alternate recipient if SCL >6
          - Alternate Recipient: CustomSpamMailbox@domain.com
          - Enable Add Subject tag if SCL >6
          - Text to prepend: S:
       - Premium - Ignore

The above is not very accurate, and will require close monitoring to be successful, even then it is not very good.  The only other functionality you can add to SMS is word blocking - which is really not a good idea.  Spammer mask obvious words like v1agr@ - or just add random spaces.  Couple the with the fact that words like cialis, are within legitimate words like speCIALISt - it can be a real nightmare.

SMS is also horribly broken in that it cannot accept wildcard addresses in the whitelists (irrespective of what symantec say) and the fact that it does not respect spaces in the word blocking (so you cant block " cialis " with spaces (so that specialist will work))

GFI has now been so successful on the gateway, I am going to move half of it to the exchange server itself (that way, I can get mail auto forwarded to the users Junk Mail folder (Exchange 2003, outlook 2003))  With that in place, I wont have to do anything at all (as opposed to the manual cleaning of over 1500 mails a day from the spam folder!)

Hope that helps

There is, in my opinion, nothing better out there to combat spam.

Above I mentioned that SMS uses about 4 routines to check for spam (RBL, Blacklist, Word and SCL)

Well, GFI uses about 50 - and clearly shows you which is working.

You can download a free, fully functional 30 day trial of GFI and see what it is like

Good luck
