We have migrated to Exchange 2013 and have set up the Anti-Spam and Anti-Malware features.  One thing I am trying to figure out is how to setup a wildcard filter for partial words.  For example, I have Viagra listed but it doesn't catch something like USviagra.  How would I set a filter for catching anything that ahs the word Viagra buried in it?

Thanks.

You can use Forefront

Using wildcard characters to refine filters

Except that it isn't supported on Exchange 2013...

Anyone have any ideas? So far the performance of the 2013 anti-spam is not good. Seems to be only catching 60% or so of the spam and going in daily to add words is a chore.
