Mail Filter set to exclusive but spam is coming through

Just today I started getting spam messages into my Hotmail inbox but my email filter is set to exclusive.  Hotmail tells me that the addresses are on my safe senders list but I have checked and they are not.  They are absolutely spam and I do not understand how they are getting through.  I see some other users are having the same problems.  I updated all of my security information which has not corrected the problem.  Seems like a bug that spammers are getting through.  Is there any resolution coming?  When is it coming?  Thanks.
