The culprit was something else entirely, which I only discovered when my 
first reply to the list was rejected with the message:

<pkg-exim4-users at lists.alioth.debian.org>:
192.25.206.28 does not like recipient.
Remote host said: 550-Verification failed for <alastair at aldavies.net>
550-It appears that the DNS operator for aldavies.net
550-has installed an invalid MX record with an IP address
550-instead of a domain name on the right hand side.
550 Unable to verify sender
Giving up on 192.25.206.28.


That's the first time I've had a message that I've sent returned to me, 
but I guess this error is much more likely to affect mail that is sent 
to me, isn't it?  So I changed the IP address to "aldavies.net" (is that 
right?) and at least one of my problem mailers is now sending me mail OK.

This would be consistent with there being no trace in my logs of the 
missing messages, wouldn't it?  In other words, my exim4 was never 
involved, since the remote mailer would never even have gotten so far as 
to contact it.

Thanks for the friendly advice,
Al

(And thanks to whoever set up the mailer with such a clear and helpful 
rejection message!)
