(jmm) Fetchmail failed to fetch

fetchmail 6.4.11
opensuse LEAP 15.2

  Fetchmail had trouble with this one message. Both fetchmail and the local mail
server blamed each other for the failure.
  The message is a trojan with a tainted XLS file; about 126KB.
  The log has the mail server's log of the transaction; it is the first part of
the log file (see below). The server was waiting (for not many bytes!?) when it
logged the connection as closed by fetchmail.
  Fetchmail sent the message header, then complained that the server broke the
connection. And proceeded to download the body anyway. And did not bother with
any of the other messages.

  My query: What happened?
