I don't think so.  The examples I've seen here have been nothing but a string 
of nonsense words, with no link or web bug.  A probe has to have some way of 
reporting success/failure, and I don't know many systems that bounce spam 
filter failures. They're much more likely to be attempts to poison Bayesian 
filters.

That much makes sense.
