I'm starting to see mail with TEXT obfuscation, such as:[...]
I heard you need viagrPa. Note the capital P thrown in to our favorite 'v' word.
It is really beginning to look like we need a genuine spelling checker, or
some sort of 'approximation' technology, if such exists.
But there is: there exists (at least in PHP) a function called levenshtein, which calculates the similarity between two words. Surely there must exist a perl equivalent to it. see: http://at.php.net/manual/en/function.levenshtein.php
