Resolved the problem!
After the warns in the acl_smtp_rcpt ACL section of the config file there
was the following lines:
accept domains = +local_domains
endpass
message = Unknown local user!
verify = recipient
I think that the verify must do a check of the static.aliases file for the
recipient. If it is found then true is returned and the earlier warn values
will then be used in the acl_smtp_data ACL part.
Thanks

Why I'm pretending to accept mail is the result of my previous posting to
exim users asking for "Help with our postmaster@??? being spoofed as a
sender address" and it stops the postmaster of our company's MTA relay (it
does the virus checking of e-mails as they arrive into the company before
forwarding them to our local MTA) sending me e-mails when I reject them
early! Doing it the way I have it now in the config file has removed a lot
of messages from the postmaster of our company's MTA relay.
