tmptitle when retrieving posts

Postie was working fine when we were last using it some months ago , maybe as long as a year. We stopped using posts on the website for other reasons but have now started again.
Now if Postie is set to manual retrieve emails it works fine. But as soon as I set it to any automated time e.g. 1 min, 5 min, 1 hour etc it brings in the email as tmptitle and no other info in the post.
here is the test for checking if the connection to the email host is working.
Would like to get this working correctly again on automated timed retrieving .
