Don't use wildcard aliases.? They break recipient validation and
cause postfix to accept all addresses.

Instead use 1-1 aliases, such as
user1 at olddomaon? user1 at newdomain
user2 at olddomaon? user2 at newdomain
user3 at olddomaon? user3 at newdomain
...

But we have 500+ addresses in ldap, surely there must be some 
'automated' way to 'transform' any incoming mail sent to 
random at olddomain.com into random at newdomain.com?

(and then have it processed regularly, so that bounces still work for 
non-existant addresses and such)

Perhaps you can adjust your query or your database to return the
desired result.? Otherwise, use your scripting skills to generate a
file, then automate the procedure.
