To configure DKIM for outgoing emails in Zimbra, you first need to generate DKIM keys. This can be done using Zimbra's zmssl tool or a third-party DKIM generator. Once the keys are generated, you will add the public key to your domain's DNS settings as a TXT record. The record will typically look like: default._domainkey.yourdomain.com IN TXT "v=DKIM1; k=rsa; p=yourpublickey". After that, log into the Zimbra Admin Console, go to Global Settings > MTA > DKIM, and enable DKIM signing for outgoing emails. Finally, send a test email and use a DKIM checker to ensure the emails are correctly signed. This will help prevent email spoofing and improve email authentication.

DKIM or DomainKeys Identified Mail is an email authentication method that tries to identify email spoofing attempts (creation of email messages with a forged sender address). DKIM enables you as the receiver of the email to verify that an email claiming to be from a specific domain is actually authorized by the owner of that domain. It is done with the help…
