Contents of an OutboundAccepted Email Log

Property Description Example
recipient Email address of the recipient. This may not be present in logs with error type Authorization failure, Reset, or Disconnected. user@example.com
sender The first email address in the "From:" header in the email message. support@example.com
action Provides context for the data in the log. Supported values for Acceptance Logs:
  • Accept: Log provides information around acceptance status for an email.

Automated processors must tolerate logs with unrecognized action values.

accept
errorType

Provides information for troubleshooting issues. This is omitted for successfully accepted emails.

Supported values for acceptance logs:
  • Recepient suppressed: Email was suppressed and not relayed.
  • Authorization failure: Email was not accepted due to authorization failures.
  • Invalid Recipient: Email was not accepted due to invalid recipient address.
  • Daily Limit reached: Email could not be accepted due to limits.
  • Sender Rate Limit reached: Email could not be accepted due to limits.
  • Byte limit exceeded: Email could not be accepted due to message size limit exceeded.
  • Reset: The client cancelled the mail transaction (via SMTP RSET).
  • Disconnected: The client connection to the service was lost before the mail transaction was complete.
  • Message parse error: Email could not be accepted due to invalid message format. Only authorization failures are logged.

Oracle reserves the right to add new values to this field as needed, so parsers must be able to tolerate unrecognized values.

Daily limit reached
smtpStatus SMTP status in acceptance logs will contain the SMTP error, or status returned to the SMTP submission client for this recipient. 250 2.1.5 user@example.com and options Ok
messageId MessageId is a unique ID that represents an email send operation. It is used to track an email end-to-end. MessageId is either provided by the customer, or will be generated by the MTA while processing email. This will not be present in acceptance logs that fail before receiving message data. 06a9aa8e-0542-4ddf-8255-ec9c2f5e02a3

See https://datatracker.ietf.org/doc/html/rfc5322#section-3.6.4 for more information.

envelopeSender The initial envelope sender (MAIL FROM) address provided when the email was submitted, which is used to authorize email sending. Unlike Body:data.sender (aka header From), this is provided for acceptance failure cases, as this is available for failures prior to transfer of message content. support@example.com
principalId OCID of the user attempting to submit email over the SMTP submission protocol. Only provided for authorization failure logs. ocid1.user.oc1.<unique_ID>
senderId

Approved sender OCID. This will be the OCID associated with the Body:data.sender if that is present, otherwise, it will be the OCID associated with Body:data.envelopeSender. This may not be present on authorization failures.

ocid1.emailsender.oc1.phx.<unique_ID>
senderCompartmentId

Compartment OCID of the approved sender. This will be the compartment OCID associated with the Body:data.senderId. This may not be present on authorization failures.

ocid1.compartment.oc1..<unique_ID>
headers (Available in future) Configurable headers at approved sender level. Set up through a support request, and is a maximum of four headers.
{
 "X-Campaign-ID":"campaign1",
 "Recipient-Group-ID": "group1",
 "Sub-Account-ID": "account1"
}
receivingDomain Email domain of the recipient. Although this is redundant with the domain name portion of the recipient field, this can be useful for aggregation views of the logs. example.com
messageSizeInKiB Message size in kibibytes (rounded to an integer with rounding mode ceiling). 5
authzOpcRequestId OPC request ID for the authorization call made from the Email Delivery Service to Identity, to authorize an approved sender. 6D6E701D166D72B8BCB7881647CDAAAA/
