Try telling fetchmail to terminate the session after X number of
messages.  Then when it starts the next session those already received
will be gone.

IMAP and POP3 do not actually do a delete on the server when a session
is still in progress.  Having fetchmail terminate the session and start
a new one will trigger the delete on the server for those messages you
already have seen.
