Postie repeditively posting from the same email

Postie is repeatedly posting an image from the same email
I can see in webmail that this email has been ‘read’ but Postie isn’t deleting it which I understood Postie would do Two other emails after this one are not read or posted either
There has been several test that worked OK, but it seems stuck on this email
