Getting Started

The Zimbra milter allows for the regulation of distribution list senders on a Global or server level. When the milter server is enabled, only users who have been granted explicit sending permissions will be allowed.

Enabling the Milter Server

     Global: Home > Configure > Global Settings > MTA > Milter Server
     Server: Home > Configure > Servers > Select Desired Server > Milter Server 
  • Alternatively using the CLI:
        # su - zimbra
        $ zmprov modifyConfig zimbraMilterServerEnabled TRUE

For a specific server (say eg.example.com):

        $ zmprov modifyServer eg.example.com zimbraMilterServerEnabled TRUE

The above steps will ensure that milter will be automatically started via "zmcontrol start"

To start the milter manually:

        $ zmmilterctl start

To check the status of the milter:

        $ zmmilterctl status 

Usage: zmmilterctl start|stop|restart|reload|refresh|status


  • The following will provide examples for granting sender permissions on the CLI:
  • User - grants a user sending permissions to a distribution list
        $ zmprov grr dl distributionlist@domain.com usr user@domain.com sendToDistList            
  • Group (distribution list) - grants a group sending rights to distribution list
        $ zmprov grr dl distributionlist@domain.com grp groupdl@domain.com sendToDistList
  • All Entities - allows all entities on the server to send to a distribution list
        $ zmprov grr dl distributionlist@domain.com all sendToDistList
  • Domain - grant all users on a domain sending rights
        $ zmprov grr dl distributionlist@domain.com dom domain.com sendToDistList
  • Public - grant all users both internal/external sending rights
        $ zmprov grr dl distributionlist@domain.com pub sendToDistList
  • After granting or revoking rights for the milter, you must reaload the configuration for the changes to take effect.
          $ zmmtactl reload

Verifying permissions for an entity

  • Checking a single user or entity:
        $ zmprov ckr dl distributionlist@domain.com userorentity@domain.com sendToDistList
        ALLOWED
  • Viewing granted permissions for the distribution list:

1) Get the users Zimbra ID:

         $ zmprov ga user@domain.com |grep -i "zimbraid: "

2) Check the permissions on the distribution list:

         $ zmprov gdl distributionlist@domain.com |less

3) Find the 'zimbraACE' entries and compare the users' id:

         zimbraACE: [zimbraId of user] usr sendToDistList
         For example;
         zimbraACE: c524877c-e0a6-4255-bb1b-d02b35cc2dd5 dom sendToDistList
         zimbraACE: 99999999-9999-9999-9999-999999999999 pub sendToDistList

Modifying and revoking grants

  • If you want to remove or modify permissions, you'll need to use 'zmprov rvr' instead of 'zmprov grr'.
  • Example of removing sendToDistList permissions for a user:
          $ zmprov rvr dl distributionlist@domain.com usr user@domain.com sendToDistList
  • After granting or revoking rights for the milter, you must reaload the configuration for the changes to take effect.
          $ zmmtactl reload

Troubleshooting the Zimbra milter

  • Verify the milters settings:
         $ zmmilterctl status 
         Milter server is running.
         $ zmmilterctl status
