This is a fetchmail question. There may be some fetchmail experts here, but the duplication happens upstream of Postfix, so this is not really the right list for this. If anyone here knows the answer, that's fine to post of course, but you may be better off asking on a list for fetchmail if there is one. -- Viktor.
