I am trying to match my reverse DNS entry to my public mail server ip
address. All incoming mail comes in fine to my cluster's smtp ip address. However,
outgoing mail uses the active node's ip address (not the cluster ip address),
so in effect I have two possible ip addresses I am sending email from (active
+ passive node). Under the SMTP Server properties in ESM the IP address is
the same as the cluster ip address. Is there a way to match all outgoing
mail to the cluster ip address? Any other suggestions? Thanks.
