if these are only load-balancers/firewalls which can be configured to port/ip no problem, only MX is restricted to port 25 because no way to specify in DNS as example we have a dedicated port with no smtpd-restrictions for incoming mails from the spam-firewall and so seperated from "normal" mail traffic
