SPAM issue

Question

Hi, 
 lately the UTM dont stop the SPAMs and send them to the exchange server and then exchange server see them as spam and send them to the junkmail folder of the end user. 
 we told to our users that they dont need to check thier junkmail folder because they will get a report when they have something in the quarantine box. 
 there are really alot of spam that been Delivered to the Exchange server and we cannot just one by one send to the support lab 
 Any idea why UTM 9.352-6 dont stop the spams? 
 
 Thanks

Those aren't, technically, spams at all. The first one was sent with MailChimp, a reputable mailing list company. Each email has a link to click to opt out of the mailings. People sign up for something and then don't remember that they "invited" the emails. Exchange lets people identify things as spam even when it isn't. 
 Just tell your users to go through their spam folder and opt out. In a few days, maybe a week, they'll stop receiving such emails.
