If the number of .QCF / .QDF files isn't so big you can just open them in Notepad (or any word processor program) to find the recipient address. If there are many files you could probably use the built-in search in Windows to search for the address in the files.
Email addresses are not case sensitive, so web.ES is an acceptable form (assuming that the domain is called web.es, of course). webES, on the other hand, is erroneous.
If these are proper messages and not spam (that frequently contain strange addresses) it could be that when replying to messages some mail clients misinterpret the sender information in the original message and create a malformed To header.
