i setup my zimbra server behind a firewall and use firewall to forward port 25,110,143 to Zimbra server.
My zimbra is working fine now..just that when at home I can not able to send mail with outlook. At office...everything is working fine.
my mta network is configured as default. I have read about the guide from here and trying to add a entry to the mtamynetworks setting there...but i got error.
ZimbraMtaMyNetworks - Zimbra :: Wiki
when I use web console to update the setting...it shows CIDR error and suggest that I should put another IP address in stead the IP address i using now?????
Please assist. my users need to be able to send and receive mail at home with Outlook.
