It has a Bayesian filter that recognizes patterns in spam messages, for example if a sender’s email address and signature don’t match, and blocks new threats based on the patterns it detects. MailWasher Pro is one of the easiest programs to use, and it is just as effective at blocking spam on mobile email apps as it is on desktop accounts. Why doesn't Outlook learn that emails are legitimate when I 'unjunkify' them daily? Why doesn't Outlook learn that other email addresses are junk and put them in the junk mail folder? Why do I get emails from senders when I've junked them? What's the best way to manage this? I'm pretty careful about where I leave my email address and with whom, but no one can be certain who has passed on my email. I have to scroll through them all to 'unjunkify' legitimate senders. I still get 200 or more junk emails a day. Some get through, others continue to go into Junk Mail. I keep clicking on 'Mark as Not Junk' on emails I receive from certain addresses. The spam filter in Outlook seems at time to be random.
