I am in the process of migrating from imail server to zimbra and I am trying to figure out how to get the reverse dns to work correctly. Currently I have dedicated IPs setup for each client:
domain1.com = 188.8.131.52
domain2.com = 184.108.40.206
domain3.com = 220.127.116.11
So when the reverse DNS is queried by the recipient server it would return 18.104.22.168 is mail.domain1.com.
So my question is how do I assign IPs to the multiple domains in zimbra? Currently they are all sent from mail2.knorrweb.com which is 22.214.171.124. But those messages are going to get blocked when they try to do a reverse on domain4.com and it returns mail2.knorrweb.com and not mail.domain4.com.
Am I setting the server up correctly? I am 24 hours into the install, and everything is working great...just don't understand multiple domains multiple ips.
