of name brands. However, MIMEDefang's origins are based on exactly this
type of concept when DFS invented it.
There are a LOT of obuscation techniques but there are also real (but

to their clients and things.
Do you have a sample of the file with the bad HTML and I can see if
there are SA rules that hit it too?
