After a whole day of testing - the problem turned out to be that /tmp
which is part of the / file system was full so empty files were being
created by exim and mailscanner was unable to write to these files.  An
error message by mailscanner (or should it be uvscan?) would have been
handy.  As this was a backup mx, it is not monitored as well as the
other systems.
