In that case, make up a fake hostname with multiple address records
in /etc/hosts, and configure Postfix "smtp_host_lookup = dns,
native". This asumes that you have "multi on" in /etc/host.conf
on LINUX systems.

Postfix will randomize the order or addresses for the "same" name
(assuming the default "smtp_randomize_addresses = yes" is in effect).

        Wietse

smtp_host_lookup (default: dns)
       What mechanisms the Postfix SMTP client uses to look  up  a  host's  IP
       address.  This parameter is ignored when DNS lookups are disabled (see:
       disable_dns_lookups and smtp_dns_support_level).  THE  "DNS"  MECHANISm
       IS ALWAYS TRIED BEFORE "NATIVE" IF BOTH ARE LISTED.

       Specify one of the following:

       dns    Hosts can be found in the DNS (preferred).

       native Use the native naming service only (nsswitch.conf, or equivalent
              mechanism).

       dns, native
              Use the native service for hosts not found in the DNS.

       This feature is available in Postfix 2.1 and later.
