I have exchange 2003 SP1. Two front end server and three backend server. Two of the backend servers are clusterd. I have to MX record. I have two ISA servers as well. Is it possible to route my out going SMTP maills through my two ISA servers with load balancing using my MX records.
Right now the out going SMTP uses my firwall check point IP address 18.104.22.168 and tries to match it with romail2.vta.org which is the cluster name. The mails get return if the receiver check for rDNS. I could put the entry romail2.vta.org in our ISP DNS refering to 22.214.171.124 which might fix my bouncing problem.
I like to be able to use my MX records for out going SMTP? Is it possible and how
