temporary name server fails

Do not why but since today after I worked some on my setup, added another dialup number to the two I had already, I get following information and cannot dial out: POP3 connection to pop.indo.net.id failed: temporary name server error. fetchmail Query status=2 (SOCKET) This ip address is what I use now with my dos email program and which I have used the last five years. It is possible that with my fine tuning I have changed something inadvertently but I have not seen anything which was not as before. Any ideas. I am running 8.2, fetchmail and postfix. My mailer is Kmail. -- NTReader v0.36w(P)/Beta (Registered) in conjunction with Net-Tamer.
