We are using a Watchguard Firebox. We are also using an exchange 2007 server.
Anti-spam is all disabled on the exchange server.
Our watchguard has a whitelist and if a domain is in the whitelist, the email should pass through untagged.
However, a lot of email is tagged [!!Spam] or [!!Blacklisted]
I am not sure what is adding those tags. Looks like it is not Exchange and the firebox literature says it uses different tags. Also, when I look at the specific email that is in the whitelist, the log says it is to pass through due to whitelist status.
We are also runnig Kapersky anti-virus.
Can't figure out what is adding these tags...
