I think there is a way....but it means you have to define who local users
are first then act on that....generate a list of local users to a file then
define the two rules like this:
# Backup outgoing
if ${lookup{$sender_address}lsearch{/path/to/local_users}{yes}{no}} is yes then
unseen deliver backup-outgoing@domain
endif
# Backup incoming
if ${lookup{$header_to:}lsearch{/path/to/local_users}{yes}{no}} is yes then
unseen deliver backup-incoming@domain
endif
Just an idea but I feel it may work ;-) Please test before implementing.
