In version 3.0 of Zimbra I was able to modify the "smtpd_client_restrictions" in the file to include a hash file, but in version 3.1 OSS it seems that this value is getting reset at startup but I can not seem to find a "" file in the zimbra/conf directory to set this value. So basically what I am looking for is how to set a smtpd_client_restrictions" value in version 3.1 without it getting overwritten.

Here is a reference to the original post for version 3.0

Thanks for the help
