Hello Mike,
except if you want high availability, smtp is a really good protocol for dns round robin.
Many isp just do this through round robin.
Is all about the smtp, or also the firewall ? If you want firewall failover, F5 is not really the good way.
You will want Cisco pix or netscreen or checkpoint (on nokia, that really rock!).
To stay on Microsoft, you can also use ISA 2004 (or 2006 in RC now), as an array to do firewall.
In the same way, you can achieve high availability trough an array of ISA with NLB, and smtp gateway with NLB.
Hope it will help,
Regards,
Mathieu CHATEAU

Kinda off topic? But I have to ask:
Scenario:
Multiple Firewalls (5) on the perimeter Single Large pipe to the INET
We need to load balance SMTP traffic to the Perimeter firewalls (SMTP is the only concern), if firewall 1 is saturated then go to firewall 2 and so on.
My question is, since I have little experience with load balancers, anyone have a short list of vendors that they have had good luck with that provides this type of load balancing? I would imagine this scenario would be pretty simple. F5 BIG-IP for instance? Or is that over kill? Just looking to narrow down a search without having to “Drink the Kool-aid” from vendor contacts……
