In this case, please stop NetworkManager and run it like so: NM_PPP_DEBUG=1 /usr/sbin/NetworkManager --no-daemon and then try to reproduce the problem, and send along the NetworkManager output. > >> 4) How can I configure NM to give me more information, said, activate > >> debug messages right from boot? > > > > Run it with --no-daemon.

At least Thunderbird, Evolution, and Apple Mail do, and that's what people should be using to reply to the entire list.
