What, no replies yet?  Or has spamassassin nobbled them all?

I always assumed the random (and therefore non-spam-related) words
were there to drown out the giveaways like "certificate of deposit"
or "prescription viagra" in various kinds of statistical filter.
That's also why they spell it v1agrá.  Oh, and phishing spams use
the random gabble to disguise the fact that the only thing that
displays is the attached image.

On the other hand, when they accidentally leave in unsubstituted
"%RANDOM_WORD" tags that tends to make them easier to spot.
