dunno what the proper is, but i temporary duplicate mails with an entry in the
alias file:
^.* : err@???, err@???

and this router:

system_aliases:
driver = redirect
data = ${lookup{$local_part@$domain}wildlsearch{/etc/mail/aliases}}
file_transport = address_file
pipe_transport = address_pipe


The obvious issue is that the envelope is rewritten and confuses the backend
MTA, so this doesn't actually work for production setups.

Alias might be the solution for your second question though.
You can make individual "routes" like that:

user1@domain : user1@internal1
user2@domain : user2@internal1,user2@internal2
user2@domain : user2@internal2


I think the actual correct solution is to use a transport with the
manualroute driver and configure it to use multiple remotehosts depending on
the localpart.
