Depends on the config. You can make postfix deliver it to mbox files (I
think that's the default), however, you can make it do anything else
that can be a transport - just override it by virtual_transport
I would define a transport table (e.g. use a SQL lookup and have a
transport field for every address), pointing to lmtp:<backend>, that
should do the job; I'm not sure about what happens to address

I'm not quite sure about the details you have, but you can mix
virtual_alias_maps and virtual_mailbox_maps at will. If you mix that
with a transport table, the latter will have precedence over the
virtual_mapbox_map conserning the transport (you could have
virtual_mailbox_transport=lmtp:<some lmtp proxy> and then override it
for some mailboxes). What I'm not sure about is whether alias rewriting
will take place in case you have an transport specified, you'd have to
have a look at the postfix docs for that.
Hope that helps,
