I have been introducing EXIM to our mailhub [1,2] (the basic SMTP routesr for
the university). I thought it all worked with the local relays tested
but last nights logs showed otherwise [I let it go live at 17:30].
------------------------------------------------------------------------------
2000-07-28 08:52:58 refused relay (host) to <gxm@???>
from <webmaster@???> H=smtp3.libero.it [193.70.192.53]
------------------------------------------------------------------------------
hsru.abdn.ac.uk is on the permited relay list and mail locally
generated gets to it fine.
Testing again this morning could not replicate the fault.

I threw in the last RCPT to convince me that some relaying was rejected.
Any ideas what is wrong? Why the test seems to work whereas in real it
fails.
