Hi, You can use the /etc/postfix/virtual file to have a list of local email addresses and their corresponding alternative address.
I'm new to postfix myself, but say you have 2 machines both configured to deliver mail for a single address g...@mail.com for example Postfix delivers mail to the local system for all it's users, but for anyone that has yet to migrate, in the virtual table, you put the email address and the forwarding address to the servers with the user like g...@mail.com guy%mail....@10.0.0.1 I had to migrate about 100 people, I just kept it all by hand and used the virtual file to manage where email went.
