There is a better way to fix which doesn't require client configuration
changes:

1.) You add the following line to "/etc/postfix/main.cf":

        canonical_maps = hash:/etc/postfix/canonical

2.) You create a file "/etc/postfix/canonical" with entries like this:

        account%machine.my@localhost.domain             
first.last%gmail.com@localhost
        another%machine.my@localhost.domain             
foo.bar%yahoo.com@localhost

3.) You create a database for the above map with this command:

        postmap /etc/postfix/canonical

4.) You use the following command to reload Postfix:

        /etc/rc.d/postfix reload

Afterwards Postfix will rewrite the addresses as necessary. You can
now even "/usr/bin/mail" and will still get the correct address.

        Kind regards
