Adding Realtime Black-hole List on Zimbra Server

RBL (Real time black-hole lists) can be turned on or off in SpamAssassin from the Zimbra CLI.

The three RBL’s that are enabled during installation are the following:
• reject_invalid_hostname
• reject_non_fqdn_hostname
• reject_non_fqdn_sender

You can set the following, in addition to the three above:
• reject_rbl_client dnsbl.njabl.org
• reject_rbl_client cbl.abuseat.org
• reject_rbl_client bl.spamcop.net
• reject_rbl_client dnsbl.sorbs.net
• reject_rbl_client sbl.spamhaus.org
• reject_rbl_client relays.mail-abuse.org

To turn RBL on
1. Log on to the server as ‘zimbra’
2. Enter zmprov gacf | grep zimbraMtaRestriction, to see what RBLs are set.
3. To add any new RBL types, you must list the existing RBLs and the new RBLs all in one command as:
zmprov mcf zimbraMtaRestriction [RBL type]

To add all the possible restrictions, the command would be

zmprov mcf /
zimbraMtaRestriction reject_invalid_hostname /
zimbraMtaRestriction reject_non-fqdn_hostname /
zimbraMtaRestriction reject_non_fqdn_sender /
zimbraMtaRestriction “reject_rbl_client dnsbl.njabl.org” /
zimbraMtaRestriction “reject_rbl_client cbl.abuseat.org” /
zimbraMtaRestriction “reject_rbl_client bl.spamcop.net ” /
zimbraMtaRestriction “reject_rbl_client dnsbl.sorbs.net ” /
zimbraMtaRestriction “reject_rbl_client sbl.spamhaus.org” /
zimbraMtaRestriction “reject_rbl_client relays.mail-abuse.org”

Note: Quotes must be added to RBL types that are two words.

Zimbra – Recreating Self Signed Signature

This article contains information for both ZCS 4.5.x and 5.0.x. Please read all instructions with particular attention to version specific sections and notes before attempting to recreate a self-signed SSL certificate. If you are using ZCS 5.0, it is recommended that you first try using the Administration Console Certificates tool, discussed further in the Administration_Console_and_CLI_Certificate_Tools Article. This tool simplifies and speeds the process of recreating a self-signed SSL certificate.
