That does not combine with the desired --keep option.

Unfortunately, fetchmail 6.3.26 cannot currently work decently in this
situation because it lacks UID + UIDVALIDITY support. There were past
contributions to add UID support but without UIDVALIDITY; so they were
worthless. Such code still needs to be written I'm afraid.
