[works!]

---------------------------------------------------------------------

But if I try to not to expunge the messages on the server after the transfer 
(using "keep" configuration option), fetchmail immediately terminates after 
fetching the first message. Don't know if this is intended behaviour?

Logfile with "keep" option set:
