In my opinion the methodology you all use for filtering spam messages is flawed. Based on my experience an individual's rules should be applied before the spam filter is used to scan inbound messages but instead you run the spam filter so that and individual's rules only to mail that goes to the INBOX. The result is that spam really isn't blocked it's just placed in the JUNK folder. The argument you all suggest is that if it's truly spam the end user doesn't need to do anything as the messages will be automatically deleted from the JUNK folder over time. The problem with that logic is that the end user must sort through lots of spam messages to discover messages that are NOT spam but were thought to be spam by filter. Bottom line is that the way you handle spam is NOT productive for the end user and needs to be changed.
Your spam filter is no longer blocking obvious spam messages as I'm now getting 20 or more messages every day trying to solicit dates with Russian women and sell me stuff I have no interest in. Just about all of these messages have a from addresses whose domains are within the top level domains of .DE and .EUS and whose addresses are all just random letters such as albrygav.de.
I would like to see a safe domain list added to the Junk Mail settings. Sometimes it's easier to make a domain safe as opposed to entering in every email address from that domain that gets tagged as spam.
It would be nice if Outlook had a why of turning off the junk mail filter on individual email accounts. My wife and I have many email accounts on many domains that feed into one Gmail account and we use their spam filter as our primary means of filtering Junk mail. Having Outlook also block junk is somewhat of a pain as I have to periodically log on to make sure that safe mail is not inadvertently tagged as junk. If you cannot turn off filtering of junk mail can you create a means by which a user could specify that any top level domain (TLD's such as .com, .net, .org, etc) could be placed in the safe sender's list so that any mail coming from one of those TLD's is not flagged as junk.
It would be nice if in your online HELP for Outlook.com you could inform users what the correct format would be to allow or block an entire domain name in the safe and blocked senders list.
