Configuration files?

[Forrest Aldrich]

I see reference to .qpopper-options and .user.qpopper-options files -- but 
what about a global configuration file?

Where can we further tune auto-delete (where want to restrict whom can 
leave-a-copy-on-server)?  I don't see that it's possible here -- and I'm 
certainly not going to go through each person's home directory and install 
a .qpopper-options file.   That would be invasive, and a bit difficult to 
maintain.
