Steps to fix NULL disclaimer on outgoing emails

Problem:

Getting NULL at the end of outgoing emails for those domains which are not configured with domain-disclaimer.

Solution:

Configuring zimbraDomainMandatoryMailSignatureEnabled=TRUE on 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 domains' outgoing emails we need to configured blank disclaimer.

With these steps three empty disclaimer files (.b64, .html, .txt) generats on path "/opt/zimbra/data/altermime/"

zmprov md <OTHER-DOMAIN> zimbraAmavisDomainDisclaimerHTML ""
zmprov md <OTHER-DOMAIN> zimbraAmavisDomainDisclaimerText ""
./libexec/zmaltermimeconfig -e <OTHER-DOMAIN>
