Actuality this is the spam filter doing it's job. The filter suspects that these three emails are spam. It's not sure if they are spam, so it is telling you, The filter put them in quarantine. If you think any of these emails are real and you want then let me know and i will release them. If you agree that trey are Spam do nothing.
In this case these are all valid emails. I released them to you and I whitelisted the senders address so they will not get caught in the filter moving forward.
