I feel you got a step forward and found out that your problem is with
fetchmail. So it would be good if you tell us, how often you call
fetchmail and how your .fetchmailrc looks like. Maybe fetching mail
overlaps. Do you keep the mail on the server? Do you call fetchmail by a
cronjob or is it running in daemon mode? If it is first make sure it
does not run while a previous process still fetches. That could be done
with a crontab line like:

*/5 0-1,7-23 * * * if [ "`ps --User remiles| grep fetchmail`" == "" ];
then /usr/bin/fetchmail > /dev/null 2>&1; fi

Set your fetchmail into verbose mode and log it's processing. This way
you can get when and why it delivers the same mail more than once to
your local MTA. Do you run multi-drop or single-drop? If unsure a view
at the mail header of a fetched mail can tell you (its in one of the
Received header lines).
