DKIM Support

Oracle Fusion Cloud Enterprise Performance Management and Oracle Fusion Cloud Enterprise Data Management environments support DKIM (DomainKeys Identified Mail). The email servers sign outgoing messages with a private key, allowing receiving mail servers to verify the signatures using a public key published in the oraclecloud.com DNS record.

Note:

Oracle's support for DKIM works for emails where the domain address is no.reply@epm.oraclecloud.com or a custom email address. To request outgoing messages to use custom sender email address, see Request Custom Sender Email Address for OCI (Gen 2) Environments in Oracle Enterprise Performance Management Cloud Operations Guide .

Get DKIM Selector Value

To find the DKIM public key from oraclecloud.com DNS record, use the DKIM Selector value referenced in the header information sent in the email. DKIM selector is referenced by header.s= VALUE where header.d is oracle.cloud.com.

For example, in the following header information of an email from sender domain no.reply@epm.oraclecloud.com: 

Authentication-Results: ppops.net; 
spf=pass smptp.mailfrom=bounces+jane.doe=oracle.com@server.rp.exampleleemaildelivery.com; 
dkim=pass header.s=emaildelivery header.d=oracle.cloud.com; 
dkim=pass header.s=ACCOUNT_NAME header.d=server.rp.oracleemaildelivery.com; 
dmarc=pass header.from=oracle.cloud.com

DKIM selector value is emaildelivery.

Get Public Key

Using the DKIM Selector value (for example, emaildelivery) and the sender domain no.reply@epm.oraclecloud.com, get the public key in the following ways:

  • Check DNS-related records from a website, for example https://www.mail-tester.com/spf-dkim-check.
  • Run the following command on Linux/ MAC OS command line: 
    dig domainSelectorValue._domainkey.oraclecloud.com TXT +short
Using the methods above, here is the public key for the DNS record for emaildelivery._domainkey.oraclecloud.co:
