How to prevent spoofing in Exchange 2000?

I am verymuch frustruated by the spoofed mails in my exchange 2000 server. Are there any effective remedies for this? I have seen some of the MS KB article regarding this, but didnt help. We are using Mcafee antispam also, its also useless to this issue.

- Are there any Exchange 2k addon to address this?
- Is there any tuning tip in exchange itslef?

Please advise a working solution

My recommendation would be to look at a 3rd party solution.

Something like GFI MailEssentials ( ~$1000 for up to 25 users)

or Vamsoft ORF (

Both have 30 day trials, I personally know that GFI is great stuff - but have received recommendations for Vamsoft from very respected people

You can also enable sender filtering to avoide spoofing

I have checked that KB Article on IP Address restriction. It gave me bad unexpected result by denying accepting some messages from other clients than MAPI, like fax software etc.

I am using Exchange 2000, so Sender filtering cannot possible.
