How To Install PolicyD on Zimbra 8.5

What is Policyd?

Policyd is an anti spam plugin. Policyd have some module like quotas, access control, spf check, greylisting and others.

Zimbra Collaboration Suite is an email server who use Postfix as engine for MTA. By default, policyd have been bundled with Zimbra from Zimbra version 7.

Why we must use Policyd?

Policyd have module quotas. This module can use for limit sending/receipt email. As example just allow sending/receipt email 200 emails/hours/users. If your email server attacked by spam or compromised password some users and used by spammer, the maximum email can be sent as many as 200 emails per hour. This policy will safe your IP public from blacklist on RBL. Besides, you can check who user send email with many email

  1. Thanks Iman,

    I added the whitelist as a sender IP.

    I have another question.. My Network Consist of 3 Network

    10.10.10.x – DMZ where my zimbra server resides and have different Public IP/ISP provider
    192.168.2.xx/23- LAN – different Public IP provider – 222.33.44.55
    192.168.1.x/24 – LAN – different Public IP provider – example 111.22.23.234

    our IP in LAN was blacklisted and a lot of users can’t send email to other mail server specially gmail/yahoo..
    my email server public IP have a good reputation, how can I resolve and prevent this?

    here is my zimbra MTA
    [zimbra@mail sysadmin]$ postconf mynetworks
    mynetworks = 127.0.0.0/8 10.10.10.0/24 [::1]/128 [fe80::]/64

    Thanks!

    1. Hello Ferjun,

      – Please make trusted network become 127.0.0.0/8 10.10.10.x/32 -> x is IP of your Zimbra
      – Block all connection port 25 from LAN to Internet and only allow from your Zimbra server

  8. HI iman
    i installed zimbra 8.7 Open source edition on Cent Os 7 – 64 bit.. SIngle server
    Is there any way to Implement Policyd on this.

    A kind request,
    your help is needed

  9. Hi iman
    The script (for Zimbra 8.5) makes the installation until the end, but I don’t have access with GUI.
    I can’t see the folder “cbpolicyd” under: /opt/zimbra/.

  10. Fro Zimbra 8.7 using this link, and after finished you will get forbidden access but don’t worry, use this link https://imanudin.net/2014/09/12/zimbra-tips-how-to-protect-policyd-webui/
    to create protection but because it’s have different folder I will give my way below ;
    create .htpasswd

    cd /opt/zimbra/common/share/webui/
    vi .htaccess
    fill with the following lines
    view sourceprint?
    AuthUserFile /opt/zimbra/cbpolicyd/share/webui/.htpasswd
    AuthGroupFile /dev/null
    AuthName “User and Password”
    AuthType Basic

    require valid-user

    create htpasswd file, username and password
    view sourceprint?

    touch .htpasswd
    /opt/zimbra/common/bin/htpasswd -cb .htpasswd USERNAME PASSWORD <—– change with your user and password
    change username and password with username/password do you want. Edit httpd.conf Apache Zimbra
    view sourceprint?
    vi /opt/zimbra/conf/httpd.conf
    add the following configuration at the bottom
    view sourceprint?
    Alias /webui /opt/zimbra/common/share/webui/

    # Comment out the following 3 lines to make web ui accessible from anywhere
    AllowOverride AuthConfig
    Order Deny,Allow
    Allow from all

    Restart Apache Zimbra service
    view sourceprint?
    su – zimbra -c “zmapachectl restart”

    1. Hi Iman and Alexander, After upgrade to 8.7 I can’t access PolicyD and follow your guide to update PolicyD and it works fine w/o authentication.
      I have 2 cbpolicyd in /opt/zimbra/ with same content and also try to change AuthUserfile to “AuthUserFile /opt/zimbra/cbpolicyd/share/webui/.htpasswd and AuthUserFile /opt/zimbra/cbpolicyd-2.0.10/share/webui/.htpasswd”
      PolicyD is working fine without password, after doing this I got Internal Server error.

      after deleting the created .htacess on opt/zimbra/common/share/webui/ it works fine again..

      Do you have any idea what’s wrong with my configuration? Thanks..

      [root@mail webui]# cd /opt/zimbra/cbpolicyd

    I did some RnD and found disabling IPv6 can cause that. I had disabled IPv6 on server so I commented out in /etc/hosts like below file and restarted services.

    127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
    #::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

    After that it worked like a charm.
    Hope this will help someone with same issue.

  15. My policy it works correctly, but there is a problem, i have 2000 accounts in my domain, but two of them send 1600 mails daily. How i can apply the police for all users except my two masive accounts?

    1. Hi LeoDelgado,

      You can configure Policy as follows

      Source : !monitoring@imanudin.net,!admin@imanudin.net
      Destination : !@imanudin.net

      The above configuration will pass rate limit if sender from monitoring and admin

  16. hi !!

  17. Hi Iman Brother,

    I did everything just like this tutorial. But I’m having problem. I can see Policyd Web Administration but I can’t see any rule there and I can’t also add any rule into it. It just happen nothing. and shows nothing. Policies Quotas everything are showing empty.

    I have an idea.. I think my database is not readable or something like this. But I don’t know how to fix this on sqlite.

    Can you please tell me how can I fix it?

    1. Hi Serazum Munir,
      Please re-populate database

      cd /opt/zimbra/cbpolicyd/share/database/
      for i in core.tsql access_control.tsql quotas.tsql amavis.tsql checkhelo.tsql checkspf.tsql greylisting.tsql accounting.tsql

  18. Hi,
    I’m having some issues enabling the WEBUI.
    See, my zimbra is set up as a multiserver configuration, so, I have a ldap server, a mbox server and a mta server.
    I enabled cbpolicy d on the MTA, since it seemed the most sensible, but now I have /opt/zimbra/cbpolicyd/share/webui on
    the MTA and /opt/zimbra/data/httpd/htdocs/ on the Mbox.
    What should I do?

  19. Hi,
    Can cbpolicyd running in multi server environment? If yes in which server i need to install cbpolicyd plugin either in MTA or Mailbox…

    Tested working fine……

  21. mas iman,
    saya sukses install policyD web ui

    apakah ‘zmhostname’ ini hostname or domain
    example : mail.testing.com or testing.com or tetap zmhostname

    tks mas iman

  23. Hi Iman if i suppose to move my policy as it is from zimbra 8.6 to 8.8 new server so how can i do this can you please guide us.

    1. Hi,
      Yes you can. You can copy/rsync policyd database from old server into new server. You can find PolicyD database from this location

      /opt/zimbra/data/cbpolicyd/db
      
  24. Hi,
    Thanks for all the help. But I am receiving a wired error when I am trying to start Apache.

    Starting apache...httpd: Syntax error on line 148 of /opt/zimbra/conf/httpd.conf: Cannot load modules/libphp5.so into server: libaspell.so.15: cannot open shared object file: No such file or directory failed.

    Well the problem speaks for itself but I could not locate any solution for that on my Ubuntu host machine. It would be very kind of you if you know the solution. As geegle’s search is bringing strange results.

  25. I followed the tutorial and was successful in enabling PolicyD and also done Protect Policyd WebUI ,but unfortunately none of the Policy is not getting saved ,nothing is getting written to sqlite db.
    Can you suggest what to do next .Using zimbra 8.8.5 and location of sqlite.db is /opt/zimbra/data/cbpolicyd/db# ls -ltr

  26. Hi Iman,
    I’m having some issues installing the Cbpolicyd.
    My zimbra is set up as a multiserver, so I have a ldap server, a proxy server, a mailbox server and a mta server.
    Follow your guide, I don’t know how to install, because I have /opt/zimbra/cbpolicyd/share/webui on
    the MTA server and /opt/zimbra/data/httpd/htdocs/ on the Mailbox server.
    What should I do?

    1. Hi Kaidou,

      You should install Policyd on MTA servers. If you need to expose Policyd WebUI, you can use Apache from system instead of Zimbra

  27. Mas,
    kalau untuk zimbra multi server install cbpolcyd nya di mana ya mas (ldap, smtp, mailbox) ?
    saya udah coba install di mailbox tp pas di restart servicenya cbpolcyd nya ga mau running tetep stopped
    kalau misalnya install di smtp cbpolcyd nya bisa running cuma web polcyd nya ga bisa akses sqlite nya

    mohon masukannya mas
    thanks

    I did everything as instructed. Now when I run: su – zimbra -c “zmapachectl restart”
    I see this error:

    Starting apache…httpd: Syntax error on line 148 of /opt/zimbra/conf/httpd.conf: Cannot load modules/libphp5.so into server: libaspell.so.15: cannot open shared object file: No such file or directory
    failed.

    Do you know any solution for this? I think without this step I cannot use PolicyD. My Zimbra is 8.6.0 in case you need to know. Would appreciate a suggestion from you.

  29. Hi Iman.

    I did everything as instructed and everything has work king good. But today when i go to web gui had an error:

    Error connecting to the database: SQLSTATE[HY000] [14] unable to open database file

    And please teach me how to fix that. Thanks!

    1. Hi Tung Nguyen,
      Please try to give permission access to your database. I am usually perform this action 🙂

      cd /opt/zimbra/data/cbpolicyd
      chmod -R 777 db
      
  30. Not Found

    The requested URL /webui/index.php was not found on this server.

    am getting this error on zimbra 8.8.9

  31. Hello,
    I configured it as in the tutorial. External receivers (gmail.com, hotmai.com) also have quotas.
    I would like to disable quotas for external incoming emails. How do I do?
