Check more log entries for these downloads - do all of them come from a mail.yahoo.com server and use the ShowLetter script? Is ShowLetter used only when downloading files? If so, you could try using a url_regex acl - something like this: acl YahooFiles url_regex -i mail\.yahoo\.com.+ShowLetter http_access deny YahooFiles If it were possible, it would be far easier to simply block the sites entirely. There was a recent discussion on blocking MSN Messenger that had a mention of blocking Yahoo mail - you could try looking for that for ideas. Adam
