How did you sniff ?
Are you using tcpdump/ethereal ?

Your Usenet client (combination of your email program and the list to
Usenet gateway) has broken MIME quoted-printable handling, with the
result that I see 56, rather than 256, although the
exact behaviour is error recovery dependent.

You haven't included the trace, so I don't know what you mean by packets
3 and 4. If you included these as an attachment, please note that the
mailing list is not the real forum, it is just a convenience for
accessing the newsgroup comp.protocols.time.ntp, which is a non-binaries
group, so should not have attachments (and any may well have been
stripped by the gateway as a result).

Thanks. Different error recovery for the invalid quoted printable, but
it still has the attachment stripped, because it was a binary.
