Bug in Gnus v5.9.0 collecting mail via pop3 with incorrect Date header

[Gareth Owen]

This is the backtrace:

Debugger entered--Lisp error: (error "Cannot get new mail")
  signal(error ("Cannot get new mail"))
  error("Cannot get new mail")
  byte-code("ÁÂÃ\b\"!„
  mail-source-fetch((pop :server "pop.freeserve.net" :user "myusername" :password "notactuallymy password") (lambda (file orig-file) (nnmail-split-incoming file (quote nnml-save-mail) (quote nil) (if ... nil ...) (quote nnml-active-number))))
  nnmail-get-new-mail(nnml nnml-save-nov "/home/gowen/Mail/gnus/" "alex")
  nnml-request-scan("alex" "private")
  gnus-request-scan("nnml+private:alex" (nnml "private"))
  gnus-activate-group("nnml+private:alex" scan)
  gnus-get-unread-articles(nil)
  gnus-group-get-new-news(nil)
  call-interactively(gnus-group-get-new-news)

This is the mail on the server that causes the error.

Point taken, that Emacs should not fail to retrieve such a message
(whether from a server regardless of the protocol, or from a spool file).
But note that RFC 2822 does require the Date header to be present, and
its contents to be both syntactically and semantically valid.

Point taken, but RFC 2822 doesn't supercede RFC 1122 :
      "Be liberal in what you accept, and conservative in what you send"
