Razor's subject: [SPAM] option

I set razor filters on a few mailboxes today choosing the option to put [SPAM] in the subject line. Then out of curiosity I was browsing the kbase and came across this article:


and it didn’t mention that option at all. I’m assuming this is just an article that’s older than this feature, would that be a correct assumption?

This wouldn’t matter much to me but, I haven’t seen any spam tagged this way yet and reading that article made it sound as though the spam would be filtered to a seperate folder which I’d need to periodically check via webmail in order to purge it.
