Easy fix: replace "[^"]+" with "[^"]+(?:\\"[^"]*)*".

Oh yes. Regexes _are_ the way to do serious parsing. All MIME packages you 
will find floating around use regexes to parse mail headers correctly.

Granted, adhering to the RFC822 to the letter is rather hard. But I have a 
sample program here that can not only parse the escaped double quote, but 
also take account for the multiple line stuff and multiple headers of the 
same type where email addresse are valid (To:, Cc:, Bcc:). See attachment. 
Feel free to use the code.
