It is becoming more and more common for spam to consist of little besides an
HTML block that points to a randomly generated gobbledygook URL for it's
content, or that contains random strings designed to fool filters. 

It would be really nice to have an option to augment the pseudo-bayesian filter
currently in Mozilla with some kind of filter that rejects emails containing
words with too many nonsensical letter combinations. 

Since this would be different for each language and possibly each user, this
should probably be an extension of the existing pseudo-bayesian filter that
operates in parallel on pairs of letters. Another good reason for making it a
separate but similar process is that this kind of operation should probably be
optimized very differently from the existing one.

Possibly a wontfix kinda bug. Too many difficulties to make this work, due to
language problems etc. as you point out yourself.

All you can hope for is that the spam messages contain enough other tokens to
qualify them as spam. Mine seems to filter VERY well, even the random sequence
messages.
