        Hi,
why also the evolution-source-registry? I'd not expect that to change
anything.

You can see what it does in the background when you start Evolution
from a terminal as this:

   $ CAMEL_DEBUG=imapx:io evolution

which logs raw communication between the server and Evolution. Whether
it'll help you to diagnose the problem I'm not sure.
        Bye,
