Hi. Have those configuration:
Zimbra server: IP 192.168.1.5, domain name mail.company.com
Send emails from relay smtp-out.provider.com
If messages are created on server from web interface and send to external recipient, example *@gmail.com - all good, but messages from server example email@example.com have error:
Host or domain name not found=name service error for name=smtp-out.provider.com type=mx: host not found, try again
I have local DNS where i have zone company.com, and have A string mail.company.com 192.168.1.5
This error have when i try to redirect admin mail to external mail...
How i can fix it?
