Normally the rewriting rules are applied in turn, in the order they occur
in the configuration file. Not in 1.62, but in the current testing release
and therefore to be presumed likely to be in 1.70, is a "q" flag that will
cause rewriting for a particular header to stop immediately if that rule
has been applied. That is approximately the opposite of what you are asking
for...

How exactly does this differ from the example in doc/spec.txt ? i.e.
*@*.hitch.book.fict $1@???
*@hitch.book.fict ${lookup{$1}dbm{/etc/realnames}\
{$value}fail}@??? bcfrF
Is it that the dbm lookup needs to depend on the host part stripped off
the front of "humber.ac.uk", as well as the local part?
