No programming is necessary; all you need is SQL. Most simply, a query which receives input of "u...@example.org" and then does a lookup of "u...@example.net". A well-thought-out SQL schema can automate this. Similarly, LDAP offers means of doing this. For those using neither SQL nor LDAP, trivial scripting can generate and maintain complete user maps. As Viktor said, while a domain aliasing feature might be worth considering for an eventual Postfix 3.0, it's probably not worth implementing here in Postfix 2.x.
