[BlueOnyx:24194] AVSpam

[Richard Sidlin]

One of my clients seems to be getting a lot of obvious spam but it's not being seen as spam by the software. I detail part of the headers from one below. It is mainly in Chinese with the senders name forged and is quite obviously spam. Are there any further settings I can change to eliminate more of this junk?

Thanks
