Not enough detail to evaluate your problem but this seems like a configuration problem on your end.
1) DKIM requires a DKIM signature.   I do not see one in your extract.

2) SPF requires the SMTP MAILFROM name, which is not necessarily visible, and is not shown in your sample (some filter products write it into the message as a custom header.)

3) Did you email to a test site or did you paste the BCC headers into one?   Your BCC message will not have anything useful for SPF or DKIM checking.  The received headers, if any, will only be the one created when Outlook submits the message, and another if Outlook uses IMAP to retrieve the message.   Additionally, SmarterMail is not going to apply DKIM signatures to an internal-only message, even if DKIM signing is configured for outgoing mail.

From & Bcc mail same address and then check header
Not using outlook ,  I am using webmail  and view source for header file

FYI -  Original domain mail changed due to security purpose

Yes, that is not a valid test.   None of the necessary information is created when the message is internal.

You get a code, send a test message to them, then retrieve the results using the code.
