I wrote last week about a maillock error I was having and I want to thank those who took the time to answer me. It was suggested that I reinstall the patches to make sure I had the newest version of Qpopper.
I had the same problem with a qube2 i kept getting lock files with qopper and had the lastest version
and then had that version problem when I tried to reinstall etc.In the end I got the source files for qpopper 4 and made that on the box and it works fine no lock files etc
