Generally, with dovecot delivery to local files, the destination domain
should be a virtual mailbox domain, not a relay domain.

    main.cf:
        indexed = ${default_database_type}:${config_directory}/
        virtual_mailbox_domain = example.com
        virtual_transport = dovecot
        virtual_mailbox_maps = ${indexed}vmbox

    vmbox:
        # When the virtual transport is not virtual(8), the LHS of
        # virtual_mailbox_maps is used only for address validation,
        # and the RHS is ignored, but must be some non-empty string
        #
        u...@example.com        ACCEPT
        ...

If the virtual users are stored in some database accessible to both
Dovecot and Postfix, use the approrpriate table driver instead of
the above table.
