Right you are. I was not aware that the line protocol was different from 
the file storage format. I have attached a snippet from tcpdump below 
and it shows a mix of CRLF and CRCRLF. Clearly the article does not 
conform to RFC 3977 which states "...an article...MUST NOT contain 
the octets LF and CR other than as part of a CRLF pair..."[Section 3.6]

One can argue both sides of this. Probably INN is more tolerant of badly-
formed articles, but the problem should be corrected at the source.
