I would really love to add an additional option to perform on filtered emails:
add a [SPAM] tag to the subject line on emails that match the filters.
Rather than auto-deleting flagged messages, a [SPAM] tag enables the client to sort the incoming emails. False positives would be on the email client itself instead of the MW trash bin thus making it a true Set-And-Forget program as you would never need to access it other than to tweak filters and lists.
One of the biggest problems is that users do not know when a false positive occurs. Its only after a couple of days passing do they realize that something is amiss or worse, they receive a phone call from an angry agent demanding a reason for being ignored. Then they have to hunt down the email admin (who may be on vacation) to go check the spam bin for them.
So please add just one more option under the Delete, Bounce, Automatically section: Add [SPAM] tag to subject line.
Thanks!
