I infer that exim is not being given the envelop address of the
sender.

Thanks David, but that was not my question. What test server is being 
takled about?

I guess that the mail server is my own machine and so try:

  $ swaks  --to <an email address> ria72@yahoo.com --from haines@histomat.net
  ...
  <-  250 STARTTLS
    -> MAIL FROM:<haines@histomat.net>

    permanently deferred; Retrying will NOT succeed. See 
  https://postmaster.yahooinc.com/error-codes
   -> QUIT
  *** Remote host closed connection unexpectedly.

Incidentally, I get 

  $ hostname -A
  lenin-16.home

that's strange. Should be lenin.histomat.net
