Navychop- You should only need rules to file emails to qualified folders. Outlook can use the "junk" folder and a rule for that for all other spam. I have just two that eliminates all my "spam" and "Phish" labeled emails to those folders. emails with attachments containing virus are screened by my virus scanner. I used to tag emails as they came in with a rule for junk so future e-mails from this source would not show up in inbox, but then discovered it was better to use one rule that tagged the "[spam]" in the header and a second rule "[phish]" to do the same. These are both sent to the junk folder. I have about 30 other rules for all my different client folders. Each day I only get a small number of inbox e-mails that need to be deleted. If I see they are repetitious and from the same source, taging it as "junk" using, not the rules but the right click options on the junk folder, handles all future inbox email from that that source once snuck by the standard spam screener.
You're right, most ends up to Junk anyway. I'll go look thru those rules and can probably trim some. But as I recall, I ended up using rules because of multiple spoofed sending addresses with similar or identical subjects. A popular ruse for a while was to use close variations of my own email address. BTW, I just looked in to my blocked senders and was stunned at just how many are there.
