Agreed.

However, with names that are frequently misspelled or which are 
commonly-spelled slightly differently, the 'trick' is to anticipate 
problems and set up aliases which forward messages to the correct address*.

eg Kelvin -> Kevlin
Niel, Neal, Neale (etc) -> Neil

(in the same way that GoodLookingGuy at mydomain -> me,
or (more likely) MailAdmin -> me)


* however, this can end-up perpetuating the mistake, rather than 
correcting...
