Someone at the local site had not configured his PC email package, so
that the From: address was x@???. Our ISP (IMHO correctly) rejected
this, as reported in exim's mainlog:
1998-07-21 16:38:00 Start queue run: pid=19089
1998-07-21 16:38:01 0yyVzg-0003p3-00 SMTP error from remote mailer after MAIL FROM: <x@???> SIZE=2018: host smtp.xs4all.nl [194.109.6.51]: 451 <x@???>... Invalid host name

1998-07-21 16:38:02 0yyVzg-0003p3-00 == daveloc@??? T=remote_smtp defer (0): SMTP error from remote mailer after MAIL FROM: <x@???> SIZE=2018: host smtp.xs4all.nl [194.109.6.53]: 451 <x@???>... Invalid host name
1998-07-21 16:38:02 End queue run: pid=19089
However, this is repeated over and over at every queue run
(200 times by now!). This isn't a temporary failure, so shouldn't
exim return it (or at least try :-) ? Exim 1.92, by the way.
This message was passed to this exim site from a secondary internal
mailhost running some old version of smail; ideally that site should
already have rejected the message straight away.
