[pkg-fetchmail-maint] Bug#383870: fetchmail: Fetchmail duplicates my SPAM every 10 minutes - ARGH!

[Matthias Andree]

Well, Exim's error before it just drops the connection isn't selling
fetchmail a hint that there's no progress beyond that point.

The question is: why does fetchmail not skip over the offending
messages? It may or may not try to bounce them, depending on your
configuration, but should mark them refused - as seen in "..flushed".

But what exactly happens is a matter of your configuration.

Please show your fetchmailrc file and the output of 
/etc/init.d/fetchmail debug-run
up to the error.

Remember to restart fetchmail afterwards with /etc/init.d/fetchmail start
