my local machine is 192.168.0.40
mynetworks = 192.168.0.32/27
so now i have given
and am getting:
zmprov modifyServer mail.bksec.co.in zimbraMtaMyNetworks '127.0.0.0/8 172.16.1.0/24 192.168.0.32/27'
172.16.1.0 is the secondary IP (internal) for the Zimbra server.
mynetworks = 127.0.0.0/8 172.16.1.0/24 192.168.0.32/27
Yeah it works now. But still have one setting to test. Because its a web client i assume I dont have to give my local network IP.
