Understanding the Playbook Configuration:

The playbook "FortiMail Sender Blocklist" is designed to manually input email addresses or IP addresses and add them to the FortiMail block list.

The playbook uses a FortiMail connector with the actionADD_SENDER_TO_BLOCKLIST.

Analyzing the Playbook Execution:

The configuration and actions provided show that the playbook is straightforward, starting with anON_DEMAND STARTERand proceeding to theADD_SENDER_TO_BLOCKLISTaction.

The action description indicates it is intended to block senders based on email addresses or domains.

Evaluating the Options:

Option A:UsingGET_EMAIL_STATISTICSis not required for the task of adding senders to a block list. This action retrieves email statistics and is unrelated to the block list configuration.

Option B:The primary reason for failure could be the requirement for a fully qualified domain name (FQDN). FortiMail typically expects precise information to ensure the correct entries are added to the block list.

Option C:The trust level of the client-side browser with FortiAnalyzer's self-signed certificate does not impact the execution of the playbook on FortiMail.

Option D:Incorrect connector credentials would result in an authentication error, but the problem described is more likely related to the format of the input data.

Conclusion:

The FortiMail Sender Blocklist playbook execution is failing because FortiMail is expecting a fully qualified domain name (FQDN).
