Mailscanner filter server to my Mail store " I just canna do it c aptain! "

[Youn Gonzales]

Load balancing via DNS does not work very well at all. I would suggest using
a hardware based load balancing device. The cisco 7200 series routers will
do server farm load balancing based on several algorithyms (sp?) and I only
mention the cisco as I have not researched anything else. I am sure that
there are better/less expensive solutions out there.
