Lay My Hat

I'm having some weird gmail problems. Since yesterday, some but not all, emails that I replying to are coming back to me in the inbox. They are reaching the guest. They are just being sent back to me. I am not BCC or CC on it, anyone else having probs?

When you use a filter with the "never send to spam" option enabled that is (accidentally perhaps) matching message you send, they will show in the Inbox.

Thanks, it did it for about 4 days then miraculously stopped thank god!
