Solved : Disclaimer not working/appear on Zimbra

Posted by

Few days ago, i asked my client to setup disclaimer in their Zimbra (Zimbra 8.6). He already setup disclaimer in Zimbra formerly by use this guidance : and this one : But disclaimer still not working/not appear while sent email. This is strange for me because i am also use that guidance and work fine 😀

After looking for and troubleshot where the problem, finally i am try to add this line in

vi /opt/zimbra/conf/

add this line in policy_bank{ ‘MYNETS’ }

allow_disclaimers => %%binary VAR:zimbraDomainMandatoryMailSignatureEnabled%%,

so that like below

$policy_bank{'MYNETS'} = {   # mail originating from @mynetworks
  originating => 1,  # is true in MYNETS by default, but let's make it explicit
  allow_disclaimers => %%binary VAR:zimbraDomainMandatoryMailSignatureEnabled%%,

save the configuration and restart Zimbra amavis (zmamavisdctl restart)

Hooray, Finally disclaimer it works 😀

Good luck and hopefully useful 😀

  1. Great guide.
    We already have domain disclaimers , when we activate the external warning , now all outbound mails get two disclaimers instead of one.

    If we disable the external warning in /opt/zimbra/conf/

    Then only 1 disclaimer is send out, as it should be.

    Any advice?
