DKIM signature fail
Hi everyone, When sending a mail on a Microsoft mailbox, the DKIM signature verification fails : dkim=fail (body hash did not verify) I do not have the problem with others webmail like GMail...
I found this : https://docs.microsoft.com/en-us/microsoft-365/security/office-365-security/anti-spam-message-headers?view=o365-worldwide
reason 001: The message failed implicit authentication (compauth=fail). This means that the sending domain did not have email authentication records published, or if they did, they had a weaker failure policy (SPF soft fail or neutral, DMARC policy of p=none).
The domain sending the mail has no policy setted for DMARC : "v=DMARC1; p=none; rua=xxxx@xxxx"
Is this the cause ?
How can i fix this ? There is no problem on others webmail.
Thx
