We just upgraded our Cisco Ironport C170 to AsyncOS 13.0. We have an inhouse Exchange 2010 server.
Now outbound emails that are in HTML format have a winmail.dat attachment.
This attachment causes some email platforms (like Yahoo) to treat the email as dangerous because of the attachment.
How do I prevent winmail.dat attachments from being included on outbound email? I believe they were stripped before in previous versions of AsyncOS.
Thank you.
