I just upgraded to Fedora 16 (this has been a semi-nightmare, as apparently an old gstreamer.i686 was preventing my complete system update from going through). But I think that I am close to having everything work.
I am using XFCE as a windowing manager.
My big problem now is Evolution. I am using Davmail to connect to an Exchange Server, so I pick up POP on 127.0.0.1:1110 and send SMTP to 127.0.0.1:1025 .
Since the upgrade, Evolution is trying to access 127.0.0.1 through a proxy.
"Error while Fetching Mail. Could not connect to 127.0.0.1: Host lookup failed: name.of.defunct.proxy: Name or service not known."
This is a proxy that was correct a few years ago, but I have long stopped using that proxy (and it has ceased to exist). In the preferences inside of Evolution, I have a Manual proxy configuration to the correct host (and a "No proxy for 127.0.0.1" exception).
The environment variable $http_proxy is undefined.
As far as I can tell, the gnome system proxy is properly configured (though there is no good tool to look at this that I can find under XFCE).
Where could Evolution be getting the idea that it shouldn't connect directly?
