Mail.app and JunkMatcher problem

Python help for Mail

I'm beginning to use JunkMatcher with Mail and am trying to train the application on different types of spam I receive. One email I received today had a very different spelling of "viagra" and I can't seem to get JunkMatcher to detect it. I've tried writing a regular expression. No dice. I'm not at all fluent in Python and the web documentation for JunkMatcher just isn't helping. Can anyone suggest an expression that would work for the following variations of common spam words?

VlljAGRA
CIjALIlS
VAjLIlUM
AMjBlIEN

Here is the expression I tried:
(?i)v\S\W?i\S\W?a\S\W?g\S\W?r\S\W?a

I assumed that would allow for a wildcard between the letters. But it doesn't work.

I'm bumping this in the hope that the thread title will update in the forum list.

edit: It didn't. Sorry for the frivolous bump.
