Load balanced SMTP servers

[Joe Brown]

We have 3 SMTP servers. Several internal apps use these for relaying. Most
of these apps only allow for one SMTP server when sending out alerts. If the
server the app points too is unavavailbe then the apps can't send out emails.
Can these be placed behind a CISCO load balancer? Is it supported? Are
there any caveats?

Don't know anything about a CISCO load balancer
Barely know anything about Windows NLB

But...

You use Windows NLB (Enterprise Edition of Server OS).
Mail enabled applications don't use the IP# of the individual
servers,...they use the IP# of the NLB cluster. The "IP# of the NLB"
cluster is always the "IP# of the NLB" cluster no matter what machines are
dead or alive within the cluster.

The CISCO product probably works on the same prinicple,..dunno.
