I have installed Zimbra 8.8.15 FOSS on CentOS 7.0. Everything seems to be working fine. Now, I want to block users from sending emails to external mail server. I checked couple articles:
  1. Restrict Users to Certain Domain - Zimbra Wiki
  2. Restrict Sending to Certain Domains - Zimbra Wiki
  3. Zimbra Tips How to Restrict Sending To Distribution List
    Some part on those articles mentioning to create file in /opt/zimbra/postfix which does not exists for me - I think the new version of Zimbra changed the structure. I found the mentioned directory - postfix in:
    1. /opt/zimbra/data/postfix
    2. /opt/zimbra/common/share/contrib/postfix
So, which one should be used?!

You can change path from /opt/zimbra/postfix/conf to /opt/zimbra/conf. It's just a path. You can save on any folder :)

If you want to restrict using web base, you can try this one : ... h-policyd/ :)
