Hello,
I have a costumer that receives an email from a service that comes with no body or subject, only comes with an attachment,... this makes Exchange 2013 block the email and we never receive it, but i can see in the service webpage that the mails were sent.
How do i override this filter or rule that blocks this specific email address on exchange server 2013, because i need to receive this emails,... they bring orders in the attachment.
Thank you !
