[horde] horde error when communicating with the server at session timeout

[Jouko Nikula]

Hello all,

I've noticed that Horde Imp displays following error message when
session times out:
"Error when communicating with the server"
This keeps coming up until user figures to logout, then in the login
page user is notified that the session has timed out and relogin is
needed.

I find this bit misleading. In my opinion it would be clearer if Imp
would immediately tell the user that session has timed out or would
just redirect the user to login page with the timeout message. Is
there a way to change this behaviour?

Regards,
