Ram Ganesh commented on CLOUDSTACK-443:
---------------------------------------

Wido,

What you are referring to with SMTP,IMAP is load balancing of mail servers etc. But what the
heath monitoring feature will achieve is health check using of backend services using either
TCP or HTTP protocols. This is similar to AWS Health Checks.
