Zimbra's nginx proxy does not handle TCP port 25, 465 nor 587 traffic; you would need to configure an external load balancer for inbound email traffic.
Zimbra's MTAs can be configure to relay outbound email through a relay host, instead of attempting to deliver external email directly. You could configure all of your ZImbra MTAs to use the same relay host. Note this would need to be an SMTP server, not just a proxy.
Hope that helps,
