Problem

The outgoing emails from the domains which are not configured with domain-disclaimer contain NULL at the end of each outgoing email

Solution

Configuring zimbraDomainMandatoryMailSignatureEnabled=TRUE at global config enables disclaimer for all domains and adds NULL as the disclaimer where zimbraAmavisDomainDisclaimerHTML and zimbraAmavisDomainDisclaimerText are still not configured.

As a workaround to prevent adding NULL from other domain's outgoing emails, configure a blank disclaimer.

With the steps below, three empty disclaimer files (.b64, .html, .txt) are generated in the path "/opt/zimbra/data/altermime/" :

Step 1

zmprov md <OTHER-DOMAIN> zimbraAmavisDomainDisclaimerHTML ""

Step 2

zmprov md <OTHER-DOMAIN> zimbraAmavisDomainDisclaimerText ""

Step 3

./libexec/zmaltermimeconfig -e <OTHER-DOMAIN>
