Hey Folks,

I work for a school district, and everything with Zimbra seems to be working fine, with the exception that we cannot receive mail from one particular district. I have whitelisted them using this:

Improving Anti-spam system - Zimbra :: Wiki

And tried to follow this as well:

IP Address whitelisting - Zimbra :: Wiki

But on the second one, I don't have this file: /opt/zimbra/conf/postfix_recipient_restrictions.cf

Here is what the logs are showing:

I have masked the actual server names and IPs...

Any help, or a point in the right direction would be greatly appreciated.

Thanks,

Weston
