Zimbra Server with DKIM Signing

DomainKeys Identified Mail (DKIM) lets an organization take responsibility for a message that is in transit. The organization is a handler of the message, either as its originator or as an intermediary. Their reputation is the basis for evaluating whether to trust the message for further handling, such as delivery. Technically DKIM provides a method for validating a domain name identity that is associated with a message through cryptographic authentication

Configuring ZCS for DKIM signing

Starting with Zimbra 8.0, the ability to add DKIM signing to outgoing mail is available. Signing is done at the domain level. Setting up signing consists of two steps:

  1. Running zmdkimkeyutil to generate the DKIM keys and selector
  2. Updating the DNS server with the public DNS entry

The zmdkimkeyutil utility

The zmdkimkeyutil script allows you to do the following:

  1. Add DKIM data to a domain that does not currently have DKIM enabled
  2. Update DKIM data for a domain that already has DKIM enabled
  3. Query the DKIM data for a domain
  4. Remove the DKIM data for a domain
