Also known as: 239, 439
What a receiving server returns after an article has already been sent by TAKETHIS. 239 means the article was accepted; 439 means it was rejected, usually as a duplicate, as filtered spam, or because the group is not carried. Since the transfer happened before the answer, a 439 wastes bandwidth, which is why feeders send CHECK first when the link is expensive.
