I made a few custom rules looking for intentional misspellings of certain subject words. We use Bayes, so of course the misspellings are soon recognized that way too.
The rules I made are based on the observation that the first and last letters of these obfuscated words are left alone to make them understandable. So a 5-letter word will have 6 possible variations, of which 5 are misspellings. Since these misspellings are highly unlikely to occur in ham, you can score them pretty high. So for this word you could use: header PT_SPELL1 Subject =~ /\bh(ron|onr|nro|nor|rno)y\b/i Of course 6-letter and longer words have more possible misspellings, so you can't extend this method too far! Other misspelled subject words I see in today's quarantine include "pretty", "lovely", and "mother".
