[Crm114-general] priolist.mfp regex problem

[Tracy R. <tre...@co...>]

I have been successfully using priolist.mfp to match email addresses that I
want to black/whitelist for ages. Now I want to block on a particular phrase
such as:

yahoo messenger online now

which is from a particularly egregious sort of spam/scam my organization is
receiving. I have tried putting the following combinations, none of which have
worked:

-yahoo messenger online now
-yahoo\ messenger\ online\ now
-yahoo\smessenger\sonline\snow
-"yahoo messenger online now"

and probably various others which I cannot now reproduce. I really expected the
first one to work. I have finally stumbled upon a combination which does work:

-yahoo.messenger.online.now

Why would . work (I'm plenty familiar with regex and know it will match
anything) but \s to match the spaces or simply raw spaces not work?

Is there some unintentional parsing being done on the whitespace I put in which
is breaking things?

Thanks!
