Three delivery attempts was made, apparently two roughly 10 minutes before your message (on 2025-01-15T02:12:26Z and 2025-01-15T02:12:33Z), and one roughly three minutes after your message (on 2025-01-15T02:25:33Z).
(Seems like the seconds aren’t being displayed, - so for clarity, 03:12:26, 03:12:33 and 03:25:33, Europe/Copenhagen (CET)).

According to your screenshot, you were asked to add the “CNAME (SPFMX)” that was named “fwdkim”.
However, -
The RFC5321.MailFrom / SMTP MAIL FROM / Return-Path / Envelope From domain that Freshworks used for the emails, it was “@fwdkim2.orientsoftware.com”.
As that (sub-)domain does not exist, the front end filtering on my mail server rejected the messages, with the status code:
550 5.1.8 <bounces+us.?.????-??LOCALPART??=orientsoftware.com@fwdkim2.orientsoftware.com>: Sender address rejected: Domain not found;
The ? marks explained:
-
“?.????”:
Represents some message specific information, such as e.g. to track the individual message’s (and/or recipient’s) delivery status.
-
“??LOCALPART??”:
Seems to represent the local part of your wanted header From: address, that recipients will see in their email client. Such as e.g. if you were using “john.doe@”, it would be “john.doe”, or if you used “billing@”, it would be “billing”.
In other words, this error is because you do not have any DNS record for “fwdkim2” (“fwdkim2.orientsoftware.com”).
None of these records are causing the error above.
If you do not have any information from Freshworks, that is asking you to add a DNS record named “fwdkim2”, then Freshworks should adjust their domain on-boarding process, as the current one in a such case would be incorrect, when comparing it to what actions are actually doing behind the scenes.
Whether Freshworks wants the exact same CNAME target on “fwdkim2”, or a completely different one, is something you need to coordinate with them.
