change IP Address of Zimbra Mail Server

[root@mail /]#  su - zimbra

[zimbra@mail /]$ postconf mynetworks

mynetworks = 127.0.0.0/8 192.168.1.0/24 [::1]/128 [fe80::]/64

[zimbra@mail /]$

In this case our postfix will reply for all machines with 192.168.1.X serious all IP address

2. If you don’t want to allow relaying for the network, but only for the zimbra server itself, configure the server like this:

[zimbra@mail /]$ hostname

mail.worldcm.net

                           zmprov modifyServer mail.worldcm.net zimbraMtaMyNetworks '127.0.0.0/8 your.server.ip.address/32'

[zimbra@mail /]$ zmprov ms mail.worldcm.net zimbraMtaMyNetworks ‘127.0.0.1/8 192.168.1.200/24’

[zimbra@mail /]$ postfix reload

[zimbra@mail /]$ postconf mynetworks

mynetworks = 127.0.0.1/8 192.168.1.200/

[zimbra@mail /]$ zmmtactl restart

Cannot Access Webmail Zimbra 8.8 from IP Address

# zmprov md worldcm.net zimbraVirtualHostname mail.worldcm.net zimbraVirtualIPAddress 192.168.1.11

# libexec/zmproxyconfgen
