Cannot post via email

I am trying to get post via email working. i have the email address to send to, mail server and password setup in admin and I am sending form a POP account on the same server as the one setup for email to post. I go to /wp-mail.php and get a message showing the email i sent was found and at the bottom “Mission complete, message 1 deleted.” but when i refresh to main site the post never shows up. Any idea where I have gone wrong?

thanks!
